So... if we're going to have this thread open, obviously the moderators are going to have some opinions about this matter.
We get people claiming we lock any and all threads that are critical about Bethesda on a fairly regular basis. My initial reaction is almost always "did you actually look at the thread titles on the top few pages of the forum?" On any given day on a newly-released game the breakdown of thread topics is generally going to be people who don't realize that we have separate sections for spoilers and bug reports, duplicate threads, and almost all the rest of General Discussion is going to be something along the lines of "here is something I hate." Drop down to something like Fallout Series Discussion and it's literally almost nothing but discussion about how Bethesda ruined everyone's favorite series and what an awful job they've every step of the way.
Basically, I think it's pretty obvious if you actually look through which threads are left open that clearly we don't lock every negative thread. Moderators are not Bethesda employees, sure, but clearly we're going to be fans of the company (I would not have been doing this something like 7 or 8 years now for a company I didn't believe in,) and of course we have a responsibility to try and comport ourselves appropriately as we are moderating under the auspices of Bethesda and the actions we take are going to reflect back upon the company. But at the end of the day these aren't my games - it doesn't affect me personally if someone doesn't like something. And beyond that we specifically know that the company's own stance is that constructive criticism is to be welcomed.
What people often get confused about is that how you present your opinion is as important as what your opinion actually is. Someone wants to make a thread about things they hate about the company or their games, that's not skin off my back. But if that opinion is expressed with a string of profanity and in a manner that insults other members or fans of the company, then yes there's going to be a problem there. And people don't get a free pass just because they're a fan - I warn people for defending Bethesda in an uncivilized manner as well.
