There are people who agree with them but they only number in the hundreds.
The Bethesda games have issues obviously. Quirky engine problems, lots of bugs and scripting issues, FO3's story and dialog weren't very good. But they were fun modern games with the FO theme. Arguing about canon is dumb considering NV went a long way to serve those hundreds of fans mentioned above yet they still found things to complain about. They probably hate life too. We're talking about a group of 40-something basement dwellers nostalgic for 90s-era isometric PC RPGs. Nothing would make them happy. Anything that came close to pleasing them would be panned by critics and dismissed by millions of gamers. The hater argument is irrelevant and Interplay in all honesty is a different company using the same logo.
