@aral Their endgame may seem to be "we want all your data for AI" but it's a touch more sinister.
Their goal: like Outlook, MS wants to push their apps off of all desktops and into the cloud so the next major releases of Word, Excel, etc. are no different than Google Workspace.
-- No more piracy. If there's no desktop apps, there's no losses.
-- AI gobbles every second, edit and save. Anything you yank back MS already "got", along with user tracking and analytics.
-- Anything made by Office is Microsoft's first and yours second (which depends on your payment status.) And like any SaaS/Cloud offering, pricing only goes up.
I kicked MS Office to the curb last spring and started using a different cloud provider and LibreOffice. It was time to get off that merry-go-round.
