It's just a business model like segmentation IMHO. BMWs or Tesla's having the hardware but require a payment for enabling it or CPU manufacturers disabling certain features to sell them at a lower price. IIRC the idea is that to let people pay what they can so you can have larger profits when allowing lower price points. In this case it appears to directly charge for a service(a software that needs to be created and maintained) that you may choose not to have.

I don't have problem with these practices at all as long as they don't try to prevent it you from running your hardware through alternative means. If the camera police isn't trying to get you for writing your own software to avoid paying Canon 5$ a month, its all good.
