I finally got around to this and jailbreaking the iPad was as easy as you suggested. Thanks, @Aatube@kbin.social!
But I don’t see how to install a newer browser. Cydia and Zebra seem to be able to install themes and tweaks. How would I get them to install Firefox or Chrome? Also, how would I install linux on the ipad?
What about an approach where there’s a website to facilitate people donating to FOSS project, and all that website needs is a list of possible recipients of the FOSS project (e.g., app developers, libraries it uses). When I want to donate I go to this website and say “I want to donate to Lemmy”, and it shows me “Lemmy has these possible recipients: X, Y, …”. When I say “I want to donate $10” the website asks “should we distribute this evenly among all Lemmy recipients?” (which might be the default) or I have the option of unchecking some recipients or or assigning some recipients a higher percentage of my donation.
