I think we kind of went off track, but I do want to clarify a couple things. There seem to be some communications issues happening. Such things can cause fractures in a community, so I'd like to address them, if possible.
I think, AiTenshi1, you are now a bit overreacting, as StarX's quoted post is a completely reasonable and polite (!) explanation why he keeps the packages on TESA - and in addition to that, he will consider to put it to Nexus, when it leaves the beta stage (or alpha or whatever).
Actually, I think it is StarX who was overreacting to a very polite, cordial question that I asked about whether or not he would ever offer his content outside of an account wall. I'm not sure how these replies could be taken as reasonable or polite. A polite response would be something like "No, I don't think I will be doing that until AV is offered publically. There are various reasons, but that's just my approach right now." I do not care why he makes such a choice when others don't. All I asked was whether or not he would offer his works openly or not. Answer: no, he won't. Okay, but there's no reason to act like anyone not wanting a TESA account is somehow backwards or needing simple tools like Steam Works.
As I said, I won't bother asking such a question again if this is the type of response to expect. I have better things to do with my time, after all, and I would think that others do, too (e.g., playing Skyrim if nothing else). I was just surprised by his replies that basically said ... well, about what Porscha says below, actually (see below for my reply to that).
People who do their own work, are the only ones allowed to call the shots to where they will have their work uploaded. Why is this even a thing? If they do not want to upload them to a separate universal file-hosting site, they don't have to. Perhaps Nexus is what StarX would choose as a mirror and that's why he keeps bringing it up. Sound reasonable don't you think?
I think it makes sense to upload your work on a host that is more organized with features such as a description field, screenshot sections, ease of updating and editing, etc. On a site that's dedicated to The Elder Scrolls at that. And if there's a problem with a mod one has uploaded, you can easily talk to members or the staff to sort it out. There's more control at your disposal. TESA has all of this.
Accounts are practically used on almost every site. Frankly, if a person doesn't want to sign up in 2 minutes to a site that's mainly about TES, all I can say is 'get with the times'.
I asked a very simple, basic, cordial question that is already reflected by others using AV. I also stated that it is certainly StarX's choice about where and when (or even if) to offer his works. I never said he had to upload them elsewhere, but only asked if he would offer them via an open site. You are repeating the very points I mentioned.

However, it is also well known that people do not want multiple accounts spread across the WWW. There are many reasons for this, some of which were posted here but others exist, too (e.g., in general, information assurance/security issues). That is why many companies are now offering login via existing accounts through other services. I would suggest that anyone who thinks that people should have multiple accounts when they are not needed should "get with the times" you know? Companies are not changing their login processes out of charity, after all. They are doing it due to user demand.
As far as preferred sites and services, there is little point in anyone claiming that one is inherently superior to another, and as I said, I never asked for an upload to a specific site or service. I saw people moaning about Planet Elder Scrolls being superior to other sites, too, but that's just subjective views. I didn't even ask for the stuff to be openly accessible, but only asked if he had thought about doing so. I also mentioned a few general reasons why people only use stuff that is openly accessible and avoid making extra unnecessary accounts. Apparently, StarX assumed that I wanted Nexus access in his replies even after I explicitly clarified that Nexus access has nothing to do with my question. Preferences in sites and services offered varies with each person, so there's nothing new there. StarX made a statement about some people (implying me or anyone who doesn't want a TESA account) wanted a "one stop shop" and that such users should use Steam Works. There is simply no reason to make such a statement in response to a very simple, reasonable question about accessibility (not to mention that the assumptions behind it are totally off-base, of course).
The main point is that there was no reason to try to rationalize why a certain decision is made when offering a reply to my initial qestion, especially when such rationalizations are made based on very faulty assumptions about the users. I was simply asking and pointing out why more people will not use the works due to them being behind an account wall. There's no problem with someone making such a choice to offer works that way, but there's also no reason to attempt to force people who know it is not good to have unneeded accounts to create one, especially when other artists offer their work openly.
So, as Porscha said, I'm not sure why this is "a thing" either. I asked a simple question and expected a simple, polite reply, but I received a response that made various assumptions about me and other users, and basically said "Get a TESA account because it's the best approach." Porscha is basically repeating the same perspective. However, that's not the reality we live in today, and many users realize the trade-offs due to having many different accounts on the WWW.
