Corporations cannot save us. Not just _will_ not, _can_ not. They are too tied into the capitalist machine, too beholden to the whims of the governments they work with, and even a truly principled stand will erode over time in light of these forces.
We should not compromise to make things more welcoming for them.
What #RainbowCapitalism _does_ do, however, are two things:
1. Acts as a social barometer.
2. Communicates broadly that "this is socially acceptable."
