not just for the obvious capitalist evil reasons but also just because how much of it doesn't fucking work at all. no matter how much RAM my phone has it still can't juggle Pokemon Go and music/a podcast. my google shopping list just stopped updating itself for absolutely no reason. random shit just constantly goes wrong and there's absolutely nothing the end user can do besides hope a fix is pushed out that doesn't break anything else
Both of my main phones (Moto Z Play [3GB RAM] and now Pixel 3A XL [4GB]) can technically play and listen at once, but if I have to pause it at any point, it always freezes for a few seconds and often it kills the player app in the background immediately, and if I manually switch back to it to start something again I have to reload PoGo when I'm done
The Z Play also sometimes just stopped the audio without me even pausing lol. Guess that's the difference another gig of RAM makes
