Haven't tried it but I just decided to put a recurring donation for aeharding on Github, Sync for Lemmy's tracking-infused ad model and the pricing for the ad-free versions just convinced me that we need to support open-source devs even more.
I find it sad that lots of people seem to be excited to pay $20 for a closed-source app but very few supported the devs that have been developing the apps that carried us on their backs until now for free.
Voyager has only 22 sponsors right now and hasn't even reached his $250/month goal on Github, while Sync for Lemmy is already asking for $100 for a OTP for the Ultra version.
EDIT: aeharding also just added a Liberapay in the sidebar!
