It won't help you with those specific cases no, but Chat Control would be the perfect tool to monitor and stop the spread of information between regular citizens who are trying to organize against the government, just look at China.

It's not your cat videos they're interested in. When people are protesting against the government it's vitally important that they're able to get information out as quickly as possible, to as many people as possible. If the government can slow that momentum down then opposition fizzles out. Chat Control would do a great job in service of that goal, it's large scale crowd control, not a targeted attack.
