Sony is presently shipping a lot of stuff with Busybox in, but they are not violating the license terms. Here you can download a zillion Sony-patched versions of Busybox to your hearts content: https://products.sel.sony.com/opensource/source_tv.shtml
The "2010 and later" section is empty. I guess it's possible that they stopped building new products which use GPL code in 2009, but somehow it seems unlikely that they stopped updating or patching old ones at the same time. If it takes them two or more years to ship the source, after they're already shipping the binaries, are they in compliance?
