Except they were careful and never actually said "we will give you money to vote for Harris/against Trump". Paying you to call him a human toilet isn't against that law.
The reward is specifically for people to come up with a plan on how they would vote. The reward isn't technically contingent on someone acting on that plan.
They were very careful in how they worded the request. They are not asking for people to change their voting behavior, only to create a plan, and to make some public statements.
Obviously, the latter part is fine but the voting plan doesn't require that someone actually change their behavior. They are definitely skirting the line, but I'm sure they had the help of a lawyer when they made this.
Disagree, people spend money with the intention of influencing the outcome of elections all the time, that's all campaign ads and canvasses and phone banks and etc. are
And they're not paying people to vote - they're paying people to make a plan to vote (and make an apology and send a tweet, but I think those are irrelevant), which is something that campaign volunteers talk about with potential voters all the time
