This website recommends Gab, Truth Social and X under the claim "Unlike Big Tech companies, which often harvest user data for profit, these smaller, privacy-focused platforms tend to resist such practices".
I remember these from their weird Twitter posting, too. I muted them because they sounded like some weird astroturfing for Twitter that kept getting recommended.
