I guess I'm wondering if these investments are due to malice or ignorance combined with laziness. I wouldn't at all be surprised if it were the latter, coming from business people.
I decided to take a quick look (ewww). I bet that it's its claim to be an "agentic OS" that's getting it all this attention. "Beautiful, fun & agentic Linux" is right on the website title. In other words, it seems similar to when any random company would get a big boost in their stock a few years ago just by adding "blockchain" or "crypto" to their name.
I also figure that another factor contributing to this attention is this DHH character's tech cred for having created Ruby on Rails and being CTO of 37signals (Basecamp). In other words, he's part of the techbro club.
I think this all makes more sense than thinking that all these companies are donating only because it's a fascist tech project. I'm sure that's a factor too, but it's probably fascism + ignorance/laziness + techbro club membership (which I guess also boils down to fascism). Ok, I just convinced myself in the end that it's mostly the fascism. :(
