He's talking about physical switches that cut power to the hardware.
I think what you're referring to with Apple is that the camera (on MacBooks) is wired in a way so that it's impossible for the camera to be on without the indicator light also being on. Software can't do anything because it's not controlled by software.
Arguably betting against their team would be way more likely to trigger the "game fixing" interpretation.
I still think their tolerance for players gambling is insane. A player (or anyone employed by the team) caught gambling on the NFL in any way should be banned for life from interacting with the league in any capacity. If they buy a ticket to a game 100 years from now, they should have the cops called for trespassing. If a TV partner hires them, it should be a breach of contract the NFL can immediately terminate their rights for.
There's no way to respect the integrity of the league if a player caught gambling is allowed to come back in any capacity at any point.
