Spoiler, they only follow court orders. You can violate the law as long as you want until there's a judge saying you do. This is just modus operandi for any big corp in America nowadays.

And right now the election court in Brazil is headed by two justices named by Jair Bolsonaro mostly for how loyal to him they’d be.

That's a plain big lie. There was no court order to ban Lula's account.

I was referring to normal business operations in the US.

So if someone thinks this is illegal, it's only illegal until a court says so. It can be in clear violation of the law but until a judge says it is they can pretend they 'interpret' things differently
