Except it’s not, you just live in an echo chamber where people endlessly repeat the misconception that the average consumer as any interest in replacing their own battery. They don’t. Marketers aren’t manipulating millions of people into thinking they don’t, either.
If companies like Apple wanted to force people to upgrade, all they would have to do is stoop to the level of the competition by not offering 6 years of OS upgrades on new phones. Or they could not offer first-party, warrantied battery replacements for ~90 dollars. Honestly, apple constantly goes out of their way to make their devices last longer than the competition, and still the bigbrains on Internet forums walk around with their heads in the sand.
You go ahead and do you homie, nobody is going to be able to change your mind from something you’re so desperate to believe.
