Commercial flight trackers encourage enthusiasts to feed them data, then take money from operators to hide that data. If you want everyone to have access to the data, consider feeding a network that doesn't censor or block anything, like ADS-B Exchange (https://www.adsbexchange.com/).
A project like Dictator Alert (https://dictatoralert.org/) uses ADS-B Exchange because the authoritarian regimes they're tracking can just pay a commercial site to hide their aircraft—they don't like being tracked.
My Advisory Circular bots (https://skycircl.es/bots/), which tweet in real time whenever they detect police, FBI, military, news or fire aircraft circling, and my "What's Overhead?" Siri shortcut (https://twitter.com/lemonodor/status/1238149529469202433) use ADS-B Exchange because a lot of the most interesting aircraft are the ones that are blocked on commercial trackers.
