I like donating to open source/software causes that I actually use. E.g. the foundations for various languages or frameworks, especially if they're somewhat niche/fledgling and not super mass adopted. I also view subscribing to a small mom & pop style SaaS over a free competitor as essentially a donation, where I choose to be monetized via cash by the small company instead of whatever FAANG monetizes me with.
