@strypey Where is the contradictory evidence? Not a rhetorical question! I haven't studied this in depth, but the main paper I know about that studied this supports the less restrictive camp: https://doi.org/10.1007/s10368-007-0086-4
There's this weird dogma among BSD partisans, which says that more "permissive" licenses make software companies more likely to support Free Code development, and pass on the benefits they receive from that license to their "end users". 25 years of contradictory evidence, that what they actually do is parasitically build proprietary software around the ongoing work of Open Source communities, has done nothing to dispel this myth.
