Of course. That would be too obvious. They write checks to lobbyists instead.

Lobbyists can't send a check to the government to buy a law either.

Lobbyists are quite literally people you pay to "influence" the lawmaking process. Through them you can essentially buy whatever laws you want. The exact methods they use are irrelevant, though I wouldn't discount the possibility that some politicians were corrupt enough to get literally bought with literal checks.

Nobody asked for this age verification nonsense. The entire child protection angle is just a way to manufacture outrage and cover up the real nature of this law. This is purely a political move from Meta against Apple and Google. Apple cut off their data via iOS privacy controls, now Meta is striking back.

Meta spent billions on lobbyists, then laws benefiting Meta and hurting its competitors were passed. If this is not evidence that you can buy laws, I don't know what is.
