Same here: Deleted my 13y Reddit account along with every other US tech account except Google, as I need that for my livelihood.
Censorship wasn't the motivation, I rather want to permanently remove my support for the US economy in any way possible, given the shocking geopolitical events of this year and the way they are treating Ukraine.
Besides, the Federverse feels like going back to the internet's roots and I'm here for it!
It should not be that surprising. Many teenagers are really smart, curious and will find their way here. That said I realise your warning is well intentioned; I hope Lemmy remains a more civil place than Reddit became over the last ten years, for everyone; teenagers included.
