The article says what he’s doing is clearly illegal, and backs it up with the law that he’s violating. He’s offering, through a lottery, a chance to receive payment in order to incentivize people to register to vote. CAH is probably treading close to the line, but I can’t say it’s clearly illegal. What Musk is described as doing seems to be pretty clearly illegal, to me.

Whoever knowingly or willfully gives false information as to his name, address or period of residence in the voting district for the purpose of establishing his eligibility to register or vote, or conspires with another individual for the purpose of encouraging his false registration to vote or illegal voting, or pays or offers to pay or accepts payment either for registration to vote or for voting shall be fined not more than $10,000 or imprisoned not more than five years, or both

Can you explain why you don’t seem to think what Musk is doing is illegal?
