Lots of companies give lots of things to "the community" for goodwill, but that doesn't mean they don't also sell to governments. Amazon gives AWS away to anyone, but ALSO tried to get the JEDI contract. One doesn't negate the other.
Corellium doesn’t charge a few “nice” researchers, but builds their business around the evil researchers willing to pay $1M/yr for a license. Clearly they’re exactly like McDonalds!
People keep making very confident but incorrect statements regarding prices offered by Corellium because they assume everyone gets quoted the same, see this twitter thread for another example https://twitter.com/therealdaneel/status/1193122030687797248
