@OrionKidder @otte_homan @pluralistic FOSS software such as GPL is an exception to this BTW. The copyleft licenses state that no license is needed to USE the software only to REDISTRIBUTE it. Even then the terms are basically that you must pass to others the rights that you got notably source code access and the right to further redistribution.

BPL v3 contains an "anti-Tivoization" clause to prohibit use of the code in devices that can only run the provided binaries and not local builds of the same binaries. This was introduced in response to Tivo using the Linux kernel but locking their devices against any builds of the Linux kernel but their own. Unfortunately there are so many authors of the kernel that it proved impossible to relicense it as GPL-3 only as too many cannot be reached. Thus scumbags like Tivo get to keep exploiting Linux.
