One sore point there is that the code comes by default with a donation link (the heart at the top) to join-lemmy.org. Even without the tankie issue it should rather go to a page local to the instance explaining donation options, and the default should be “The admin didn’t set this up, if you urgently need to get rid of money here’s a link to Doctors without Borders”.

OTOH there’s now a huge influx of people including tons of developers so I expect tankie influence to be drowned out sooner than later.
