That assumes that the market itself is actually "free" and consistent and that there are no bad actors in the mix, and upstarts are allowed to freely start and compete. Given the regulations in the space that is emphatically not so.

Incumbents will remove and enshitify a number of features in order to maximize returns... Your new clothes dryer has a 10 year mechanical warranty.. but the control board isn't covered, will die in 12-24 months and won't be produced again. Oh and there's some clunky DRM in the mix on top. Guess you get to buy a new dryer, but this time you'll go with $OtherShittyBrandThatDoesTheSameThing.

Aren’t newer washers/dryers full of electronics because of laws mandating higher efficiency? My parents have an old Maytag washer that uses around 30 gallons per load while my washer uses less than 8. I know Speed Queen makes dumb laundry machines, but at least one of their models was banned for residential sale by the Department of Energy. They ended up figuring out a workaround by gimping the default cleaning mode and encouraging users to not use that mode.[1]

But I don’t see how mandating removable batteries helps this situation with phones. I don’t replace my phone when the battery degrades, as it’s pretty cheap & painless to replace the battery after a few years. I upgrade when my phone stops getting security updates, or when a new phone comes along with some feature I want.
