Copyright laws are a good thing, but when they become abusive, then they do a lot more damage than having no copyright laws at all.
I suspect that using a platform where there isn't any way to profit at all is a better solution. But in this case, the CR owners have probably been burned for years and just don't want to have any more discussion around the matter. It is easier to just say no.
Finding solutions that make it harder to say no seems like a better goal... of course that probably means paying them.
If this were actually true, then all these other platforms wouldn't exist.
