I'd like a dead-simple and globally accessible way of donating.

Like github/gitlab/etc allowing to easily deposit money via CC, Paysafecard, Google Wallet et al. The projects could have a "donate" button by default.

I often clone and browse projects and absolutely wouldn't hesitate to donate a few dollars here and there if it's just a click away.

Flattr does this, sort of. I pay a monthly fee and it distribute it to whatever repos I star that month. They distribute to more than Github as well, but not everything.
