Literally everything I buy on the internet has features unlocked by higher payment plans (Netflix, hosting, ahrefs etc). I don't get the big deal about it. For one, I am happy I can upgrade my car without any mechanical interventions. You get what you pay for when you buy your car. It's their business if it's limited down to meet your package or not. Did they deliver anything else from what you paid for? If the answe…
For internet-based services like Netflix (or Spotify or Youtube or whomever), more stuff (streams, bitrate, resolution, etc) has higher costs for them: bandwidth, storage, licensing. They don't provide a physical good necessarily, but that doesn't mean there's zero cost to providing a higher-grade experience to their customers. (LTT has a whole video about the cost of serving 4k and 60fps video from their independent video platform that's a pretty good primer on this space, IMhO.)
In the car scenario, the cost is already sunk: the hardware is in the car, the capability to go-fast is already there and it costs nothing further to the manufacturer to allow the customer to use it. Putting a cost on it is the literal definition of rent-seeking: they're not creating anything new, which might justify the cost, they're just charging you to access a thing that already exists.
Especially since it's an ongoing cost for a thing you already own. Imagine if this extended to every other product: You buy an ipad with 1tb of storage in hardware, but you have to pay Apple $15/month to use it all. You buy a 4k monitor, but you have to pay Dell $5/month to use it at resolutions above 1080p. This doesn't make sense, and it's plain corporate greed. Mapping physical goods into the "As a service" world is absolutely nuts to me.
