You are on the wrong site if you think that HN was ever a bastion of the hyper OSS mindset.
This is a site powered by and run by one of the arms of a startup incubator/investor. It has always been clear on that.
Just because it has “hacker” in the name doesn’t mean what you think it means.
From 2010 ... https://news.ycombinator.com/front?day=2010-10-04 that still looks similar (though I find it amusing that Ask HN: So what's new in the world of A.I.? https://news.ycombinator.com/item?id=1754134 is on the front page "... My prediction (heh pun intended) is that you see enormous changes in the field when processing by GPU's becomes much more available.

There's certainly been some broification and the various reddit exoduses have been shifting the average user a bit.
I do believe you've got your top color set to ff007f rather than ff6600 if you're forgetting what the site looked like then.
I've certainly thrown together more software and automations over the last year than I have in the other ~15 years since I started programming.
It's never been so fun.
