The selection of countries seems so random. The poorer countries seem to be in favor, no judgment there... It looks like a pay-off list, though.

The whole thing also played like a game. 6 months ago the vote was signaled as pretty safely against chat control. You could watch how one by one the MEPs switched their positions. I assume they realized the vote wont hurt them because it's under the radar of general population. So it was safe to follow the lobby money.
