Technically you can just setup a political party and then offer membership in the party for a yearly fee like 100EUR - every member will automatically become a politician and thus won't be allowed to be tracked because that's literal exception in the Chat Control. If government will want to track them, it will need to expand tracking to themselves too, which they definitely don't want to do.

So now government is not allowed to track you and you can also make quite a lot of money out of this stupid law.
