Pretty poor evidence generally, mostly on the say so of snake oil salesmen trying to convince political campaigns to pay them handsomely to do so with extremely uncertain results.
I note the conspiracy theory that Cambridge Analytica threw the Brexit referendum via Facebook has essentially completely collapsed over the last month or so. CA certainly wanted their clients to think that such a thing was possible. They were fantasists, for money.
Short term, yes, but what guarantee does any political group have that the tech companies won't turn on them at some point? Facebook in particular has an ever graying userbase, which means they're naturally going to continue to lean more and more conservative.

I don't buy it. Facebook has always been an adult network. It started as something that kept kids out. They opened up, but they dont need them. Eventually, when people get older they sign up for it. It't not sexy, its utilitarian. Their biggest risk to their business is more addictive products, not their customer age. People can get addicted at any age.
TiKTok, Instagram, Twitter, Youtube are still more commoner<>celebrity networks, while Facebook is a WhitePages and now a YellowPages too.
From what I see, it's less important with young adults now than it was a few years ago, and it started as something only for young adults that spread upwards through the age groups. It could be reaching a stable point though, true.
The whole "facebook isnt cool anymore" thing has been going on for a decade now. Linkedin isnt cool. The WhitePages arent cool. Plenty of other properties, like twitch, discord, twitter, carve out their niche. Snapchat was going to be the facebook killer, people got bored with snapchat. But facebook keeps growing. Now TikTok is looking like a threat. But no matter what everybodys favorite place to hangout is, they also have a facebook. And companies keep throwing money into facebook ads.
