And at this moment in time, the "best" strategy is to milk customers with recurring purchases. And it turns out the value-add didn't work. So feature-removal-and-sell-back recurring purchase is the current phase.
We're seeing that everywhere in IOT, gadgets, kitchen consumer gear, vehicles. Basically, it's the manufacturers exerting control post-purchase with the implicit threat that they can and will brick your stuff.
To put bluntly, we need government oversight over these realms. First-sale doctrine needs to cover "functionality sold at bill of sale". "No bundling" (of additional services that "complete" a thing) also needs to be strongly enforced. And if/when companies do stuff later and remove features (PS3 for an easy example), that they need to be dealt with as if a hacker did that - as C-level ordered felonies with prison, direct massive compensation to the wronged parties, and massive fines (company-ending if need be).
