This is not just about those two but the general trend. Charities are the new tax havens since the panama paper debacle. there aren't many hiding places anymore. What most wealth managers advice (and i know a couple in Switzerland) is to shell through a charity and then trickle back up to other companies once the storm passes. even without a storm this is big tax protection.
Switzerland started the trend and in fact many blockchain companies are registered as such. I believe the latest Tezos sham had to do with the company being supported by a shell charity.
I didn't even mention the obvious warnings that are thrown in popular networks as a flag. and for a good reason.
