I think if you take a step back and try to fight against confirmation bias you'll see that the arguments you're making are very weak.
You are also moving the goal posts. You started with it was sketchy to claim a namespace now you're moving to it's sketchy to own domains. Of course people are going to buy variants on their domains.
This is easily in the top 5 most toxic moments in open source, and off the top of my head seems like #1. For all you know this is some kid in a country with a terrible job market trying to create a resource for the community and get their name out there. And the Zig community tried to ruin his life because they whipped themselves into a frenzy and convinced themselves there were secret signs that an AI might have been used at some point.
I've never seen an open source community gang up like that to bully someone based on absolutely no evidence of any wrong doing except forgetting to include an attribution for 22 lines of code. That's the sort of issue that happens all the time in open source and this is the first time I've seen it be used to try to really hurt someone and make them personally suffer. The intentional cruelty and the group of stronger people deliberately picking on a weaker person is what makes it far worse to me than the many other issues in open source of people behaving impolitely.
This is an in-group telling outsiders they're not welcome and, not only that, if we don't like you we'll hurt you.
And yes there have been repeated mentions of their interest in crypto, including in this thread.
