@ambiguous_yelp @dalias @sammi @joelanman I'm going to be real with you
I think Veritasium is kind of an idiot. He never seems to know much about what he's talking about. He's probably not a good source.
Also, persistent IDs being an issue are only an issue depending on your threat model, & you can always have dummy IDs (persistent IDs are actually helpful to me this way, I can create two separate "identities") or throw away your current ID. Except with Signal!!! Signal doesn't let you do this!! I hate that Signal doesn't let you do this!! This is my only issue with Signal! Signal fits my needs almost perfectly, just this one issue. Even Discord lets you have multiple accounts & it's completely plaintext.
