It doesn’t even apply to software standards lol. It’s a dumb “playbook” probably made by some coked out Microsoft middle manager in the 00s that wasn’t even widely successfully used. Lemmy’s crappy example of it is Google “killing” an extensible messaging protocol, which is nonsense because they didn’t kill anything (you don’t “kill” a protocol), they extended it into a proprietary version. You know, because it’s extensible.
The only relevance “embrace, extend, extinguish” has in today’s society is as an excuse to spread FUD and ragebait on Lemmy.
