And for that matter, AviSynth got bit **hard** when supporting more than
just 32-bit x86 became necessary, so any early success in attracting
plugin authors by having a Classpath-style exemption was quickly offset
by getting stuck with those decisions to maintain compatibility, and
suffering a lack of established plugins on new architectures/platforms
due to how many authors in the early days kept their plugins closed 
(thankfully most(?) of the regularly used and useful plugins now are
under FOSS licenses, but I don't even know how many plugins exist that
simply can't be ported because they're essentially closed-source
abandonware tied to an ancient version of AviSynth).

So it's just as much of a cautionary tale about how not to set up plugin
licensing and how the upstream handles compatibility in regard to it.
