Puzzles me why anyone defends steam. Steam is a great place to buy games, but it is a horrible feature for playing them. It adds nothing to a single player game, there is no beneficial side to it, there is only the downside.
Probably for the same reason people would wonder the reverse.
I have no issues with steam. I know no one personally who has had real issues with steam. Ever. Period. Not saying that it svcks to be other people, just that I have No reason to complain. Steam is a service and nothing more IMO, Big Deal. I think people's energy would be of better use if it was directed at complaining about bad design decisions IN SKYRIM... and not as much the 3rd party service it comes with.
There are people who are having legitimate problems and that is one thing. If it dies on you occasionally, or your upset because when it resets you have to set yourself back to offline mode... well okay: Complain away. You are having an issue that needs to be addressed. I'd go to the steam forums and raise some hell, put a block under it, don't leave there until you get banned.
That said: The vast majority of complaints I keep reading aren't about what is wrong with the service, it's what COULD go wrong with the service. At that point, it's all just paranoia. Steam could one day reverse much of it's policy, sell all your information to Ethiopian con artists, crash it's servers intentionally, lock all play into required internet access, put spyware on your computer so that you can ONLY play steam games, put spyware on to search for Pirated softwares it then reports to publishers, Gabe Newell could drive to your house and eat everything, Or the whole mess could become sentient... You've got me there. Also, tomorrow the sun could explode, the singularity could happen, bubonic plague could kill 1/4 of the population, the US could arbitrarily decide to invade Poland, and I could be crowned King of Sardinia.
You can then say: "Well, because all those horrible things could happen, we shouldn't use steam at all!" Which is all well and good, but not entirely realistic. I don't know for sure, but I would bet anything the majority of PC copies were sold over Steam. If that is the case, almost all titles sold on steam require steam to install. It doesn't make a lot of sense for Beth to exclude steam from their product, if that would limit the number of units it sold. Beth makes games, they seem to enjoy making games, but they are also a business. You can do both, but to do so successfully you can't stunt one end or the other of that equation.
GoG was mentioned above, but one thing to that: GOG did mostly out of date games until just recently I believe. I was surprised when they put Witcher 2 out on that service. Of course a lot of things surprise me about Witcher 2... Further, GoG is a great service, but you can't say that if they sold exclusively on that service, they would have had as much success with PC sales.
