Politics free cores?
The advantage of open source code and cores is that "it belongs to all of us" -- you're not going to get any of those "Entity List" problems when some politician has a brain fart. The choice of a core or a piece of code IP is often a commercial decision, you don't choose something because its the 'best' but because its most suitable for your business. Now we know that a lot of closed source IP carries significant commercial risks it makes sense for people to avoid using it unless there's absolutely no choice.
One of those foreseeable side effects of meddling in commercial technology but, as we all know, you can't tell politicians, pundits or other Type A sorts anything -- they know everything, they don't need to listen to lesser folk, just the sorts that know how to stroke egos.
