You've all missed something.....
Sure the boss has come up with these MBT "solutions" and there's loads of kits left from shutdown projects. However, a good BOfH will repurpose said kits for other things. Sure, he'll tell the boss that the IoT junk was removed and is now in a storage bin.... but some of that kit will have had potential, will have been repurposed and will now be doing something off the books. a great BOfH will keep such repurposings secret. Bitcoin mining would have been done, he's not going to mention that, it's beer money after all!
