ACG employee here so grain of salt, etc - but I paid for an ACG subscription long before I worked there.

My favorite piece of ACG actually isn't even the courses, but "Cloud Playground", which came over in the recent Linux Academy acquisition. [0] One-click AWS, Azure, or GCP sandbox environments. They're live for 4 hours on ACG's credit card and people sometimes assume they're just for doing course labs, but, like, you can use them for whatever. It's an end run around sandbox account procurement in a business context, or a safeguard against leaving an expensive resource running for personal experimentation.
