It already exists. There is a company that sells a space heater that mines crypto currency. You get like 50% or the profits which sucks, but you at least recoup a bit of the cost of the electricity to run the heater.
I think we should try to heat ourselves with computing as much as we can since the side effect of computing is heat generation (and minor RF losses). How cool would it be to make a large supercomputer out of millions of homes heating up in the winter?
Playing devil’s advocate here but there could be legitimate reasons to prevent features of an app if you don’t give the permissions.
Things like professional type apps that need geolocation to work (geofencing, photo geoloc) or because x big shot client wants to track their employees and you’re just forced to accept that unless you want to declare bankruptcy.
Definitely is a very hostile pattern though and there’s no reason for meta to do this shit…
