Nah. It's been at least since 2009 (GBC), if not longer.
It started happening with the advent of applicant tracking systems (making hiring a nightmare, which it still is) and the fact that most companies stopped investing into training of juniors and started focusing more on the short-term bottom line.
If the company is going to make it annoying to get hired and won't invest anything in you as a professional, there's 0 reason for loyalty besides giving your time for the paycheck. And 0 reason to go 120% so you burn out.
The problem, as I see it, is the changes that bug me [1] seem systemic throughout the economy, "best practices" promulgated by consultants and other influencers. I'm actually under the impression my workplace was a bit behind the curve, at a lot of other places are worse.
[1] Not sure if they're the "actions" you're talking about. I'm talking about offshoring & AI (IHMO part of the same thrust), and a general increase in pressure/decrease in autonomy.
Devs are hired goons at worst and skilled craftspeople at best, but never professionals.
