Maybe we need a new movement (or revisit past ideas from the 70s) that focuses on ensuring the openness regarding freedoms of computing (😉) that combat proprietary SaaS offerings? idk.

This is why OSS as an org needs a change IMO. Licenses like SSPLv1, where software can be supplied for free with options that allow a company to make money without risk of a cloud vendor snapping up their software (think Redis, MongoDB, etc) need a place at the table.
