You might have said why you feel this way before, but can you go over that again? Arguing that Skyrim and Morrowind are similar is one thing, but trying to say that Skyrim actually has more in common with Morrowind than Oblivion is another thing entirely. As far as I'm concerned, there's a pretty broad consensus that Morrowind and Oblivion are at least similar, but Skyrim went off in a different direction.
I listed several long ago and I kind of don't want to rehash them all. I definitely respect some of the other viewpoints with regard to which one is closer to Morrowind.
Here are just a couple:
1) I thought that Oblivion thrust the main quest upon you. Once you start off, your destiny is handed to you (literally, with the Amulet of Kings) by the Emperor. You're given this destiny as something you "must do" to save the Empire and the world, essentially. To me, that broke role-playing instantly. I couldn't, in good conscience, walk out of the sewers and say, "Ah, well. Time to open up a shop somewhere" or "I think I'll go and hunt". The quest was unavoidable. Not only that once you went to Kvatch, Oblivion gates popped up everywhere marring the otherwise beautiful landscapes and forcing you to close them if you wanted to rid the landscape of them (which became so repetitive after a while). The main quest was "always" in my face. Morrowind, when I stepped off the boat and registered, like Skyrim, I was given a lead on where to go and who to talk to, but I wasn't handed the Amulet of Kings and told that it was my destiny to save the world by the Emperor who had such a significant dream. I didn't have to go and speak to the captain of the Blades (forgot his name) after getting registered in Morrowind if I didn't want to. Same in Skyrim, if you don't want to do the main quest, nothing binds you to it at all. You can forgoe it and not feel hounded by it. It's perfect for role playing. Dragons are not nearly as tedious as Oblivion gates.
2)Skyrim seems smaller in scale than Morrowind but larger in scale than Oblivion. And this is just a personal opinion that others have shared with me... I have the sense of open-ended discovery and adventure that I had playing Morrowind. Much moreso (largely because of being "bound" from the beginning to the MQ) than Oblivion.
3)Skyrim brought back the Morrowind character model types. Elves (high, dark, wood) look more like they did in Morrowind. Using Oblivion's character creation engine, I could make a high elf look just like a hot breton with pointy ears. It seemed too LOTR to me. The elves are ugly as hell in Skyrim, just like they were in Morrowind. The Nords are tall as hell, etc.
4)Dwemer didn't inhabit Cyrodil. One of my favorite things about Morrowind were the Dwemer ruins. I was tickled with glee when I stumbled upon my first one in Skyrim and I love the fact that the deeper you delve the more you run into those disgusting swine, the Falmer... a pleasure to chop up. I understand that Oblivion had the Aelid ruins (I can't remember the exact spelling), but I wasn't crazy about them.
5)Oblivion's enemy levelling system irritated me in that, where bandits used to roam, Minotaurs, Minotaurs, and more Minotaurs gradually replaced them as I levelled up. It got to the point where I thought there was another nation of Minotaurs that had invaded Cyrodil and was threatening to exterminate all mankind. The enemy levelling system in Skyrim reminds me more of Morrowind than Oblivion. There seems to be a wider variety: stronger/weaker, different types where you'd expect them, etc.
There's more, but I don't want to write a book.
