@luka That matches my experiences, honestly; I've found that getting donations or not (which that essentially boils down to) mostly just has to do with asking someone in the right way at the right moment, *after* they've enjoyed the thing in question, and then lots of people are perfectly happy to just donate with nothing in return!
@luka (The "moment" thing is what many 'traditional' donation-based things get wrong; they frequently ask for donations *before* you've downloaded or watched or listened to something, at which point of course someone has no reason to want to donate yet)
