"A whole bunch of folks ignore copyright terms, so all complaints that 'Inhaling most-to-all of the code that can be read on the Internet with the intent to make a proprietary machine that makes a ton of revenue for the owner of that machine and noone else is probably bad, and if not a violation of the letter of the law, surely a violation of its spirit.' are invalid."

When I hear someone sincerely say stuff that works out to "Software licenses don't matter, actually.", I strongly reduce my estimation of their ability to reason well and behave ethically. Does this matter? Probably not. There are many folks in the field who hold that sort of opinion, so it's relatively easy to surround yourself with likeminded folks. Do you hold these sorts of opinions? Fuck if I know. All I know about is what you wrote today.

Anyway. As I mentioned, you're late-career in what seems to be a significantly successful career, so your reputation absolutely doesn't matter, and all this chatter is irrelevant to you.
