Didn't we have one of these a few days ago?
From the rules:
8. The only criticism that is allowed here is constructive criticism and that is welcome.
Constructive criticism criticizes a proposed idea. Criticism that is directed against one person, be it a modder, another member, an individual developer, a certain moderator or a group effort are all forbidden.
This means that when you voice your concerns, please do so in a way that offers a vehicle for improvement. If you see something going wrong, feel free to say so, but also say something about how to set it right.
It also means that posts that run down other members or factions among the membership who may not agree with you are still out under the rules against flaming and flamebaiting.
Emphasis here on "group effort" (and maybe "developer", but it's a little ambiguous whether it means a single development studio or one member of the development team, probably the latter.)
So if you don't want your thread to end up locked, I'd expand your complaints to include specific examples. What specifically don't you like about their games, and what could they do to improve them? "Poor" and "Dumbed down" are just flamebait, they don't actually mean anything.
That said, I don't see anything particularly wrong about their approach. Overall, they're still making critically acclaimed games. The only big complaints I see are about Dragon Age II and the ending of Mass Effect 3, which they tried to fix for free. The first Mass Effect was a good game, if a little boring the second time around. I haven't played the others yet but mean to. I own Dragon Age: Origins but have yet to play it. I don't have any right to complain, but I don't see what I would complain about. Is it just the cool thing to do these days?
