UBI needs to be administered by the government. Opt-in at a private level creates some weird dynamics, not least of all in the legal relationship between participants and the intermediary.
I would be critical of such a program even if it was proposed by a stable, highly-visible organization. A kickstarter is a huge red flag here. I hope the existing investors land safely.
I had the same thought, so I put the article’s URL into Ground News: 6 sources talking about this story, with popular.info being labeled as “high factuality”.
Pleasantly surprised, I guess.
