Kinda silly argument TBH. If you find value in the service just use Bitcoin. They will eventually see it's pointless to support shitcoins and go Bitcoin only. You can be the signal. They will follow what the market wants.

It's like avoiding all supermarkets because they sell vegan food 😂. No, just send a signal by just not buying their vegan shit that's it.

So, what's your alternative? According to them, most of their sales are in USDT, so maybe you could blame it on bitcoiners for not paying in bitcoin more often.

I don't understand this stance of disliking shitcoins but being OK with fiat. Unless you somehow manage to pay 100% of your expenses in bitcoin. If that's the case, please share how you do it.

Exactly like @clr said, why would you @Syturio not be okay with allowing shitcoins to life? It's not like you're paying all of your expenses with bitcoin, just a weird argument, honestly.

Also its not open source, so no F-Droid. Too bad, the use-case of Bitrefill is sound.
