Ideas spread between humans. On systems designed to facilitate communications between people, these ideas will likewise spread. Did AfD exploit TikTok's algorithm or is right wing populism seeing a large growth worldwide?

When the printing press come out and certain news agencies starting "Yellow Journalism" were they exploiting that system of communication for profit?

Did JFK and Nixon exploit TV for their own political purposes?

I believe wholeheartedly that every social media algorithm should be open source and transparent so the public can analyze what funny business is going on under the hood.

But is it any different from how TV channels pick what shows to play or what ads to run? Which articles get printed and the choice of words for a newspaper?

I think people are quick to jump on TikTok because of some unusual socially acceptable jingoism but I don't see how at its core is fundamentally different from other forms of media, let alone other popular social media platforms.
