In the US, the politicians need money to be elected in the first place, and a lot of it. Lots of money comes from the big tech (to both parties), and the big tech won't give money to anyone with a plan to "rein them in."
Every evil propaganda corp has a cutesy brand name like that. Names like Voice of the People, or Electoral Freedom Foundation, or Moms for Liberty, or Free America Foundation or First Amendment Recovery Temple (I definitely made that one up, and some of the others).
It's not that "money can buy votes," but for a given party money can buy facilities (offices, transportation, food, etc.) and people (activists, coordinators, etc.) and that can bring (not buy) votes. Printing one "Rodriguez 2027" sign and putting that on your front lawn can be done for free at someone's office; printing ten million of them is a major financial, logistical and organisational undertaking, all of which costs money. Printers, truckers, warehouses, coordinators don't care how many "fucks" you're giving; they just prefer being given dollars to being given "fucks."
Maybe you have more ... workable (?) solutions than "let's get everybody to give a fuck and vote in a different way"?
That's why political parties were invented, so you don't need to create name recognition for every candidate.
Those signs aren't changing anyone's mind. But a party is something people can talk about and understand. It's unifying.
Giving a fuck means engaging with party politics and making it part of your day to day life (at least during election season).
Signs are the laziest and most inconsequential way of supporting a candidate. By far the best way is to convince everyone that you know in person to vote for a particular candidate.
In 2016, just 400 American families were the source of 50% of all election money that year. If your "candidate" is going to "rein in big tech," how the hell are they supposed to raise money from them? And if they aren't going to do that, where will that money go?
Your views seem to be rather ... idealistic. This TED lecture[0] is only 18 minutes long and it offers rather a chilling perspective on any sensible reform.
