gollark: It's actually worse than *just* that though, because of course.
gollark: There are some other !!FUN!! issues here which I think organizations like the FSF have spent some time considering. Consider something like Android. Android is in fact open source, and the GPL obligates companies to release the source code to modified kernels and such; in theory, you can download the Android repos and device-specific ones, compile it, and flash it to your device. How cool and good™!Unfortunately, it doesn't actually work this way. Not only is Android a horrible multiple-tens-of-gigabytes monolith which takes ages to compile (due to the monolithic system image design), but for "security" some devices won't actually let you unlock the bootloader and flash your image.
gollark: The big one *now* is SaaS, where you don't get the software *at all* but remote access to some on their servers.
gollark: I think this is a reasonable way to do copyright in general; some (much shorter than now!) length where you get exclusivity, which can be extended somewhat if you give the copyright office the source to release at the end of this perioid.
gollark: This isn't really "repair"y, inasmuch as you can't fix it if it breaks unless you happen to be really good at reverse engineering.
