It is plain that the Democratic Party doesn't want Sanders voters if they're going to demand Sanders policy outcomes. There's no drama in successfully helping people, and what kind of partisanship isn't made of drama?
It is plain that the GOP didn't want Trump voters until Trump more or less took over the ticket with the help of professional-class journalists looking for... drama.
Presumably, if proprietary code isn't linked with GPL code, it's not a derived work, but two separate works under different licenses. If your situation can tolerate it, you might could write a gplserver running in a separate address space. Or, if it's hardware to hide, video drivers frequently provide a razor-thin kernel driver that does little more than let you mmap the device's I/O space, with all the action sequestered in a proprietary userspace library.
