Agreed on the former. As for the latter, that's hard to tell from the outside. No you can't go back, but if the suffering reliable outweighs the joy, a dignified exit should be supported, and the only one who can really judge that is the one going through it.
If there's maybe enough to hold on for, try holding on. If there's a chance for improvement, please try holding on. If there isn't, then there isn't.
Either way, I hope for improvement in the future, be it personal or medical. No one deserves this kind of suffering.
No but you see we at Google aren't locking down sideloading. It's the individual app developers. With the api we gave them for that express purpose. Totally not us locking stuff down though, so EU please ignore us trying to indirectly close doors in our walled garden?
