Same. I get value back from FR24 in the form of a Business subscription which gives me a TON of data and access I wouldn't be able to afford. I fed ADS-B Exchange for nothing because it seemed like a nice thing to do to benefit the wider tracking community. To have the founder cash out and sell OUR data without even talking to the community first? That really rubbed me the wrong way. I stopped feeding about an hour ago.
I'm interested in a lot of different forms of transportation as a hobby. Photography, tracking, etc. Being able to see the flight history of a specific airframe is interesting to me or going back and looking at past flights. Fleets is another feature I use. For example, I've been interested in trying to get photos of the new E915-E2 jets that Porter Airlines is adding so I've created a "fleet" and can easily track the whereabouts in the hopes of being able to catch one in flight to photograph.
