I wish you were right, but that's just not how the EULA for WoA reads.
It's a very tiny portion of their business, and a non paying one no less. I'm not sure either way, and really, until I can buy a license, I probably will ditch WoA. The Insiders/Dev ring is more of an annoyance than a help. I have other machines than my M1 to do all I need.
Yeah, I've wondered about that too. I guess they don't have that kind of granularity between installs on Intel and on M1. Anyway, it's gone on my M1MBA now btw, the last update must have got rid of it.
