The video you posted is ummm not really the type of editing we're looking for.
If your other skills are any better, you're always welcome to help the team.

My rule of thumb when dealing with mud throwers:
1) Check who it is, have they EVER DONE A SINGLE THING TO HELP THIS PROJECT?
I'm sorry jupiter, but you haven't contributed, ever.
Buying a speculative asset doesn't make you a contributor.

2) Check if they actually make some valid points.
Note: this only applies to technical aspects. The team doesn't waste time answering comments on "communication, how we should manage our project, overly repetitive questions".
If they haven't ever contributed and they aren't making any sense then I discard their criticism immediately.
If you package your criticism in a way that is constructive and you are actually willing to help us yourself by doing it: hop on board!
