I maintain a few very different packages, and have had some good experiences and bad experiences. What I maintain ranges in size and complexity from Javascript libraries, database add-ons, and virtual synthesizer modules. I've dealt with hostile users, and hostile packagers, but ultimately I've stuck with it due to some quite incredible challenges and communications I've received, ranging from very difficult problems that they've reached out for help solving, causing me to rethink some solutions, to very nice notes asking if it's ok to use software that I released as building-blocks (what it was designed and specifically licensed for). But, there are still those people that I dread hearing from, that make me want to just stop -- thankfully there are enough of the other kind, and interesting problems, to keep me going. As for donations - I have only put donation links on the virtual synthesizer modules, and have received a grand total of $5, not exactly game changing, but worth a pint of beer. So, I maintain for another day, maybe not as actively as some would like, but at least at a level that keeps me from burning out on it.
