yes it was a twitter clone spawned by one of the many Musk dramas, which basically looked and worked like someone rolled something in php 2000's style, on a shoestring budget 😀 

which it was, the idea was that it was run by some organization with by-laws that would prevent the excesses of twitter like data harvesting, algorithmic rage boosting, advertisement, abuse of moderation and so on, but they didn't have any plan at all to cover costs

and not surprisingly, went out of business quite quickly
