I don't think we're going to agree on this.
Electricity shut down hunting whales for oil, cars shut down horse whip makers, etc. That's just progress. Like shopping malls, Blockbuster, buffet restaurants -- everything has its time.
There are more games being decompiled now than ever before, and the leap in accessibility is tremendous. While this may dilute your community and its practices, and while it may look like an Eternal September, it is bringing orders of magnitude more people into the fold. And that's worth a lot more than you're giving it credit.
Math, science, bio, and certainly CS and software engineering are going to change. That's progress. Nothing should stay the same forever.
I'm happier to see the world morph into something exciting during my lifetime rather than have slow and modest progress up until I die. I feel a bit like the people who were born early enough to witness the Wright brothers and who ultimately lived to see people walk on the moon. I'm glad tech is doing something like that rather than just having decades of uninspiring incrementalism.
I'm sorry you don't share the same outlook, but I promise there's a silver lining in this if you look more closely.
People are going to get closer and closer to owning their technology. The value of code is plummeting, and that means that in time these claims over our software will erode to nothing.
I would focus your energy on making sure we have open weights parity with the foundation models. We need to have a seat at that table. That is the real threat to our freedom and future, not petty IP squabbles or software rights.
