Which amounts to “if we like you” and “we reserve the right”. If they wanted these patents to be open source, they would license them explicitly.
A high profile company like Tesla is not going to want to be seen suing two high schools students using an electric motor to power their Tanzanian school. But they want to reserve the right to stop the White Supremecist Indy 500 team using the same engine.
Seems like the best of a bunch of good and bad choices
