Yes, you can criticize Team Cherry, but you shouldn't be toxic about it
Look, I know that we are all upset about the lack of communication with Team Cherry, I am too and think that they should try to communicate more with the community even if it's just to say that they are having troubles with development or anything like that, so it's normal that you want to voice your complaints in hopes that Team Cherry does something about it.
What's not ok, however, is to be extremely toxic about it, because there is a very big difference between giving constructive criticism and yelling complaints like "I hate Team Cherry", "They don't deserve their community" or "I will pirate their game once it comes out" because by doing this you are accomplishing literally nothing, so please don't waste your energy whining like a little kid.
And I still respect Team Cherry, sure I'm a bit upset about everything but they still gifted us an amazing game that many of us still play years later, and not getting any news on some gaming events (which btw, that's on us and the fake leakers for creating unnecesary hype) will not make me think less of them.
So yes, say anything you want about Team Cherry, just please please do it in calm and kind way, because we are definitely better than this.
