There's a bunch of other requirements you need to meet and no one cares about RAM consumption. So you do it the most time efficient way, not the most memory efficient.
Before you scorn, doing it the opposite way, taking more to use less memory, makes you less promotable, not more.
Why exactly? Because all the people who really care about good software will switch over? All 1% of the market?
Most people don't care about most things. I don't think much about the vast majority of products I use, because there's only so many things I can track closely. Same goes for everything else. Most people won't look and won't care.
I've heard SO MANY people who wouldn't usually care about such things say unprompted that they hate Windows 11. The ads, the nagging, the unbelievably slow performance for things that used to be instant, the terrible taskbar, etc etc.
I think they've finally made it so shit that people actually care and will look for alternatives.
Maybe it won't happen today, maybe not in the next 5 years, but it will happen.
