I think it requires consensus on a larger level to allow this to happen. According to what I remember Roger having said once, there are BitPay employees getting paid in bcash. In other words, more people than just the shareholders are in, and thus very likely have no problems at all with these twisted policies.

The problem I have with donating to the more recognized mainstream charities, is that in most cases you end up having to fill in so many personal details that it just isn't worth it to me. Years ago there was an option to either donate 'anonymously' or donate and fill in the details that also allows you to claim a tax refund. Probably related to shitty regulations.
