I second this. However, Funkwhale does not integrate directly a support system as far as I know.
FairCamp is probably the best support tool as you're supporting directly the artist (minus the payment processor fees, I guess?).
On the other hand, not everyone is willing or has the possibility to set it up.
The second best might be https://mirlo.space which is also a "Bandcamp-style" kind of thing. Still somehow acts as a middle-man, but for non-techy users is quite a breeze to use.
