> it's only admissible for hiding machinery from the general public.
I had originally read this to imply that somehow it's OK for a casino to hide its machinery from the general public, but it's not OK for TikTok to hide its machinery from the general public, but maybe "machinery" here is intended much more narrowly, and OP thinks it applies neither to casinos nor TikTok.
