> Chat control is bad, but it was voted out multiple times already, and is fundamentally incompatible with several member states' constitutions (based on a comment, didn't read more into it, but I believe Romania and Germany, among others).

Why on earth couldn't the member states vote for safeguards AGAINST initiatives like that, so they can't repeatedly keep trying?

Because for some shitty reason the EU is set up so only a consortium of governments can propose laws, then an elected parliament only says yes or no but can't propose its own laws.
