Domestic abuse
When I hear "I was wrong, I learned I need to change" from someone who's been abusing someone else for so long ... all I see is a wife-beater saying "Don't go, baby, it'll be different from now on." It's still an abusive relationship, and it always will be.
If there's any reason Micros~1 "loves" open source now, it's because they're slowly moving everyone into their NEW monopoly: the "Microsoft 365" and "Azure" clouds. Those who take the bait will continue to be abused.
