Neither Levine nor Spector have sold out. Spector just has the luxury that he can do whatever he wants. He's a big Disney fan? Fine, let him make Epic Mickey! I don't blame him for it.
Game designers shouldn't be stuck in a hole just because some vocal fans have "expectations" from them. Like everything in life, people change their tastes, preferences etc.
Levine is imo a no-nonsense guy. When somebody interviews him, he tries to at least making sense. He's not that Dave Gaffe guy or CliffyB that thinks "Yo, let's blow **** up bro!" is the apex of the medium.
There are really only 3 companies left that do immersive FPS/RPG/adventure hybrids with no ingame cutscene narrative: Arkane, Irrational and sister studio 2K Marin. I buy all their games day 1.
