Follow the money.

like if EU countries themself decide to undermine their own rights thats their thing

but if external powers try to undermine EU constitutions isn't that a attack on those countries and shouldn't that be a crime, if not punished else wise at least punished by exclusion from lobbying and if not respected by exclusion of the EU market as a whole?

sure freedom of speech, including lobbying, is VERY important. But there is a big difference between external powers trying to take away rights of EU citizens and internal powers doing so and that is also quite different to what lobbying is made for (trying to avoid making laws which are "accidentally hurtful"(1)/have unintended side effects or are simple not viable to practically comply to(2)).

(1): Like actually accidentally/unintended harm, not a reasonable law some company can't comply with because their whole foundation is based on idk. customer abuse.

(2): Where it's not the point of the law. If a company makes money by causing mass harm through a legal loophole and that hole is closed it should never matter if they can comply with it.

Can we also please start a corruption investigation into politicians involved, politicians which have repeatably tried to undermine their own countries constitution (weather on country or EU level) shouldn't be allowed to just go one like nothing happened and try again a year later.
