Is there any good free ADS-B platform these days? I know adsbexchange got bought up by a private jet charter company. So I guess they'll start blocking all sorts of stuff.
One of the best is https://airplanes.live/ - which currently aggregates data from nearly 1700 feeders globally; they have a legal agreement preventing sale of this data (to avoid situations like with adsbexchange); they share the data on a selective basis.
One of the largest ones, Opensky Network - is supposed to be open for research purposes but they refused my request straight ahead.
They got bought early 2023 according to the website, if they're not already filtering data, why would they suddenly start doing that? The company that bought them don't seem to be mainly a jet charter a company, but describe themselves as a "Aviation Market Data" company.
