Nope, just worked on it as a private citizen. (Don't have an account with any Meta service.)
In an ideal world, we'd regulate social media. I've tried and failed advocating for privacy legislation--the people who are passionate about privacy in America, unofortunately, also tend towards political nihilism, which makes the cause a political nonstarter. I'm also concerned about Chinese influence over American society, and care about Taiwan's security, so TikTok sort of aligned between my views on privacy, teen mental health and national security.
