Focusing overly on corporate structures or specific skills tends to miss the point of how value is assigned in a capitalistic structure when knowledge is cheap. Knowledge has been the capital used by the labor force for hundreds of years. The reason some jobs are resistant is 100% the result of legislation at that point, not anything unique about the job.
"The Trades" seems to be the sales pitch used on the public. In the end they're just labor at that point since I can pump a 20 year old with a master electricians knowledge, keep one master on staff and fire every other person who hits that level when their earnings demand it in the same way we're firing many mid/upper level people in their 30's and 40's now instead of 50's and 60's which is the scenario in Tech today.
Software/IT is just the quickest to be absorbed. Many other industries are just in the slow boil, not seeing it yet.
There is a mutual agreement between all collaborating parties that "hey we ALL need these core fundamental building blocks of software. why dont we all collaborate in this open space?" And everyone wins.
There is tremendous value in the Linux kernel, and these large open source programs. And this is basically an attack by corporations to attempt to privatize it all.
It's nothing new. This is simply the latest example of capitalist "growth at any cost". We sailed past any immorality hazards a LONG time ago.
