"The OpenSky Network is a non-profit community-based receiver network which has been continuously collecting air traffic surveillance data since 2013. Unlike other networks, OpenSky keeps the complete unfiltered raw data and makes it accessible to academic and institutional researchers."
For what it is worth, I don't actually know what the PE company bought. I guess the historical data and a rack full of servers - but the staff, community, and service are moving elsewhere.
Here it feels more like people are providing unpaid work (by running receivers) and who in their right mind would continue doing that for a commercial entity.
Most people with a smartphone. I do enjoy more precise GPS even if it means Apple and Google are soaking up Wi-fi hotspot info to improve triangulation. I think the difference is most people don't realize they're feeding this info to companies.
Instead of everybody uploading their data to one dude who can sell out, instead flood-fill it. We're not talking about a lot of data here.
It is actually a massive amount of data. Gigabits per second that need to be aggregated, sorted by geographic region, fed into multilateration systems, and cleaning the output before it can be shown on a map.
