As is, the generator itself is a self-contained unit that requires no real specified MX other than to be replaced when the shelf life/expiration date comes up. The remainder of the system has periodic checks for condition and operation of the automatic or manual deployment function.
I don't know what the fear-mongers think can be done with an O2 generator, but it take a few tools (and a bit of technical understanding) to get to, and remove, one without activating it. IIRC, the only 2 things really produced by the generators is O2 and heat (other by-products were not mentioned in training).
