To be fair, writing apps that tries to throttle the use of memory is harder as you might have to let go of unused data onto disk instead of read and forget or process data little by little instead of all at once.
So, as soon as devs realize their apps fit in 1GB or something these days where even mid range phones have 4GB of RAM, they see no reason to optimize further.
