It’s shifts like that, going from a copyleft to a copyright crowd, that make me increasingly suspicious the HN is authentic as it was years ago. Another weird one is the socialism lean instead of more libertarian ideals by many commentators. I think it might be generational issues and being 50+ years old makes me an old timer!
I'm guessing it's because every year, younger people join HN. I've been on this site for at least a decade and a half with various accounts and it's interesting to see the shift.
