Facebook and Instagram are the worst offenders in my experience too, but is there really anything that would prevent them from repackaging and selling their solutions to other companies? Or a competitor attempting to make a copy of it?

If I've learned anything from looking at competing products over the years, it's that every company will attempt to lower itself to the bar of the worst but successful company. And if uBO developers give up, that's blood in the water all these sharks can smell.
