Soon, activists will start boycotting Microsoft (gov't agencies use Word and Excel), 3M (gov't agencies use Post-it notes), and Charmin (they also buy toilet paper).
Big difference between making general purpose software like MS is and making software specifically for a specific purpose...
There have already been calls to boycott cloud providers for providing VMs in the cloud so no, it seems there's little difference in the eyes of some people.
One protests where they can, and where it's feasible. In this instance, they were in a position to turn down a company that not only makes software that is directly used for purposes they don't agree with, but whose CEO has a viewpoint they strongly oppose (in contrast with Microsoft, 3M, or Charmin, which support in a very indirect fashion).
I've been boycotting Angle Soft for political reasons. Not that anyone cares.
What is angle soft, and for what political reasons are you boycotting it? Maybe if you provided more info, people would.
It is toilet paper manufactured by Georgia Pacific a subsidiary of Koch Industries. I don't have a car because I can work from home so I mostly walk or bike keeping healthy although doing it for environmental reasons. I also boycott refined sugar in protest against mismanagement of sugar cane production runoff in Florida. Nobody cares about that either, however, I've lost a ton of weight since and my dentist says that my teeth are perfectly healthy, so there is that.
