Well, under this interpretation all lobbying basically circumvents sovereign democracy, there's nothing out of the ordinary I found out in this article other than business as usual.
And the thing is, lobbying by domestic and foreign interests has been so normalized, that most people are already numb to it. Like Putin was even visiting his Austrian politicians buddies who then got jobs at Russian oil and gas companies after their terms and nobody in EU kicked much fuss about it when it was all done public and in the open and in 2022 we got to experience the consequences.
So as long as nobody from politics is going to jail for treason or insurrection, or at least lose their seat and generous pension over such blatant cases of corruption and treason, this will only continue or even grow larger, as those in power have proven to be unaccountable to anyone.
I don't know how we(the public) can fix this peacefully an democratically, as any party I can vote for gets captured by lobbyist interests who seek to undermine our interests.
Lobbying is part of the democratic process. There are many interests in society and it is right that their voices be heard and considered by the government and parliament when deciding on law and policy.
It is important that there be rules to keep things transparent but lobbying is not a problem in itself.
A simplistic example might be: Let's say that a group calls for a ban on all vehicles then it is right for groups relying on vehicles to make their voice heard to explain what the negative impact would be. Once government and parliament have heard all sides then they can make up their mind. If whole groups are banned from expressing their point of view and from defending their interests then it is no longer a democratic free society.
Interference by foreign powers is a different thing altogether.
Calls to ban lobbying are the usual "slippery slope" that leads to authoritarianism.
This _is_ democracy. Europeans don't vote left and green.
Those groups have only 235 seats in the EU parliament out of 720.
