Look at what happened with the Arab spring in Egypt... after the leaders fell, even worse parties and fundamentalist strongmen came in. It was lauded as a democratic revolution until the muslim brotherhood came in. Same shit happened in Syria -- now it's devastated.
There is so much outcry over TikTok being adopted in masse within the United States -- this isn't really that different. Facebook invests a lot of resources fighting fake news in the US -- I doubt it puts any efforts into propaganda (nor has the ability) that is spread in a place like Turkey.
The way to think about these countries behavior is -- imagine foreign governments were sending the KKK $100 of millions along with weapons across your borders. We got a taste of 1% of this with Russian interference -- but it is nothing compared to what happens in the middle east.
