back in the place between 70s-80s we used to identify commercials with an audio compression detector, blank frame detector, generally a device that detects artifacts of the ad process. then we could record on a VCR without ads as we went about our day.

it was a cat and mouse game eventually with programs being salted to spoof ad detection, regulations requireing a broadcaster to have some demarcation between ad and program, and on...

streaming has one fatal flaw, that decides final ownership, and that is eventually, the content is in the clear, in a space accessible to a technichal user, that can be replicated, and fitted with the requirements for a persistent file, and thus "pwnd".

at this point the ad can be snipped out, and is gone.

its a bad model, ads should be part of the content, depictions of product usage, and consumption, as part of the content seemed like an unobtrusive, actually pleasant association, every time ive seen it done, vs some screaming loud volume, shocking switch of subject and mood associated with a product that you dont need, and will subconsciously avoid as a result of the operant conditioning.
