The MIT License, Line by Line
Licenses like MIT and BSD should be avoided due to the patent risk in favor of licenses that explicitly grant patent protection like Apache 2.0. The patent troll risk is just way too high. As rando said, companies like Microsoft are even open-sourcing code while raking in hundreds of millions from patent suits against open-source software. That this is even working for them shows the permissive licenses need to eliminate that tactic entirely.
