> Laws are only as good as their enforcement

The claim is that those licenses are deemed no-touch within those companies—it's the companies themselves that insist on the software and their business not mixing, e.g. Apple continuing to ship old versions of GNU programs like Bash and then eventually moving to zsh rather than provide updated versions that are GPLv3.

Neither GPLv3 nor AGPLv3 say anything about businesses not being able to use the software.
