But also a challenge. Linux also has to introduce purely Microsoft/Google/whatever-account log-on (without explicit local user log-in preceding it) as an option because this is what many zoomers expect. You just give them a new computer, they sign-in with their account and start doing their job. Businesses they run also expect this when ordering computers/integration from you.
The open source world actually needs to implement this + a decent offline alternative to Alexa or be left behind.
I will never want to use a Microsoft/whatever account either but other people will.
