While you're maybe not wrong about it not changing the election outcome, I just wanted to say that it was more than a few Facebook ads. Russia was the likely source of the DNC email leak. Also, it was a lot of sock puppeting and co-opting large groups on Facebook and also Twitter and Reddit. Hundreds of people, masquerading as thousands, playing both sides off each other, all day long every day for months. There were groups for every demographic imaginable, swaying them, as appropriate, to stay home because Hillary doesn't care about [ethnic group], or to vote for Jill Stein because Hillary is just a neocon in disguise. Or to vote for Trump in protest. Or to vote for Trump because conservative.

It was a well funded and coordinated effort by a nation state. Not a few thousand dollars on bad english ads.
