Nice list!
My theory is that if we start with an up-to-date list, we can crowdsource updates without too much trouble. In theory?
One way to do this could be to have a GitHub repo where the list is hosted. That way if someone wants to update it, they create a pull request that can be accepted by the moderating team
Matrix still doesn't have a multi account client with threads.
I don't mind Matrix, but every time I bring this up to a hard core Matrix defender to how the clients are lacking, they don't have much to counter.
