Don't lock it down. Just buy a cheap phone, populate it with inane stuff like pictures of food and travel.
Create a puppet Instagram/facebook account and do the same, and don't install WhatsApp until you're past security.
Better yet, don't visit the US. Who knows how much more fucked up it will get as time goes on.
Perhaps.
I mean, it's not like YouTube creators are happy with the state of the platform either. They keep getting paid less and less to the point that they have to resort to begging for donations or include sponsorships in the videos.
I imagine at this point other platforms are well positioned to capitalize on what YouTube has been doing to the platform for some time now. Personally I really like what platform aggregators like Grayjay are doing: basically the idea of following creators, not platforms.
So you can just install Grayjay now through their website and you'll be surprised by how many youtubers you follow are already on other platforms.
