Getting the diverse, opinionated and variedly incentivised open source communities to agree on thinking as a unified "something" is like herding cats. But its high time that the desirability and existence of an "opt out" is recognized formally and that won't happen without large scale coherence.
Maybe even the notion "open source" is not longer helpful towards that end. Big tech has inflirtated and one way or another "sponsors" pretty much every major open source initiative.
The starting point is data sovereignty and privacy, but more fundamentally, what we need is agency in the use of information technologies.
