I hope community won't shut down every criticism
There will be a lot of stupid hate comments everywhere (Already saw some in today's gameplay videos), but there also will be a lot of normal criticism.
Devs need, no, they NEED criticism so they could know what needs to be changed, improved, fixed and such.
Saw a bug, especially critical one? Report it to the devs and tell community about this so they could spread the word.
Saw something you dislike and you think that removing this stuff will greatly improve experience for many players, or vice versa? Tell devs about this and also community so they could spread the word.
If criticism will be silenced like it's just some hate, and if community will just go with "Nah, the game is perfect! <3", then... the game still will improve, but not greatly.
