For me personally, it's because I never use my laptop without it being plugged in. There's nowhere I would want to use my laptop that I can't find an output (home, work, planes, airports, friends' houses, etc.)
The only exception I can think of is when actively riding public transit, but I never use my laptop in those situations.
A lot of laptops are also bought by people's employers and are a tiny cost that no one cares about (~$1,000 every 3 years for an employee making $300k+ in that amount of time). They don't care if the battery degrades.
The only time I ever cared about battery life on a laptop was in highschool where it had to last all day without being charged.
It’s like buying a car with tires that last 50k miles, but if you want to replace them you have to cut off the entire drivetrain and weld on a new one. Technically possible but only with excessive effort.
I think that car manufacturers can borrow a lot of bad ideas from IT: not being able to own a car, instead just renting it from the company, artificially gimping it and requiring a sum of money to "unlock the features".
Tesla already did this
Tesla also has a monthly fee to unlock rear heated seats in the Model 3.
I didn't realize. This kind of thing is really lame. In my case it wouldn't matter at all but for some reason it really rubs me the wrong way.
