On the one hand, I think Tone is decided that just about everything is a scam or not good enough. On the other, there is a big difference between a pure currency and token/currency tied to a particular service.

I can understand if Tone doesn't want to people to think he'll get a wallet for and accept just about any crypto token or stock as payement/donation. That would be highly unpractical for him and also bring quite a bit of added risk.
