Developers don't get paid for information, ads, user data, or per-install / purchase on F-Droid. As a very general rule, apps are uploaded to F-Droid because people made something fun or helpful, and they want to share. Their incentives ("I made something fun!") align with my incentives ("I want something made by a dev that can at least pretend to give a shit about the user"). Apps are not inherently user-hostile, or made for an ulterior motive.
Proprietary app stores are... nearly as much of an exact opposite I can think of, regardless of who sponsors them; Microsoft, Amazon, Google, or Apple, devs are putting apps there to get paid. Sometimes it's user data, sometimes it's "Free" with in-app purchases pushed by dark patterns, sometimes it's to push for consumer lock-in, and sometimes it's straight up malware, like most flashlight and cleaner apps on Google Play. Regardless, the incentives don't align, and that is what I'm on about when I use the word trust here.
People don't like it when a UX change is made by and for the company that just so happens to screw lots of users, or break or slow their usage. That's exceedingly rare on apps made by devs in the first category, and depressingly common for the latter group.
