This... Is a really weird take. Really. Maybe, just maybe, people want to dedicate full time to OSS? Maybe they can't find a job? A donation is just that, donations. Quite different, I think, from a tip, in that there is no cultural pressure to donate as there is for tips. If you don't want to donate, don't. But don't complain when people kindly ask for them. (Also, a tip (especially online ones) is very different because, unlike a tip, you actually know the donation is going towards the entity your donating too, instead of you not knowing if the tip is going to the person it should be going to or if it's going to the company operating the service.)
