A politician needs to give big tech something other than money to get their messages to be favourably targeted.
Don't forget that they already have access to virtually infinite money through abuse of market dominance, the only thing that can stand in their way is antitrust and data regulation.

You used to be able to send socialist ads to socialists and conservative ads to conservatives... and be everything at the same time and win. Its like a cheat code of politics.
Now to do this you have to promise Zuck to not support any antitrust and data protection regulation in return Zuck will probably take you to office by microtargeting. You don't need to worry about the media, facebook will "fact check" everything for you.
You can still target nonpolitical ads based on other attributes if it is not specific to very few people.
