I contribute 2% of my annual salary (after taxes) to the software I use personally, $360 of which goes to the continued development of Lemmy. The splits are uneven and depend, primarily, on how much I feel the project needs money. For example: I participated in Bonfire's Indiegogo campaign, but I have only ever given Mastodon, like, $5 once.

Professionally, I make sure my company makes donations to the FOSS projects we use in production. It's less than they deserve but more than I can afford out of pocket.

If you put all those contributions together, they wouldn't sniff even $10k annually. But then again, my company and I don't have nine figure revenues.

You?
