You get the "Pro" apps from F-Droid, including the "ThankYou" App. I never got any nagging from them (and yes, I donated, but that did not have any technical consequences and is not necessary).
I want to recommend things everyone benefits from, not myself. Consequently, I don't want to support anything that doesn't trend the community toward my ideals.
For instance, the Mastodon project and mastodon.social are run by a non-profit. They have their own mastodon account which discusses updates, advertises merchandise to support them, and could ask for sponsors or donations if needed. Users can subscribe to their feed if they want, and support them should they need help, while users who don't want advertisements won't be affected. I'm confident in the stability of this model for them so I chose to make my Mastodon account on their instance so I can trust I won't have to transfer to another someday should one shut down.
I'm hoping the digital space evolves in this direction and that we approach a post-advertisement economy.
Otherwise, enshittification keeps ruining things and we can't rely on the long-term stability of anything. Just look at Google.
