I bought a gps app several years ago after testing it out on my phone. It had everything I wanted and was fast and smooth on my phone. Next year I wanted to use it for a long trip but then it was updated, they had rewritten it from scratch. Most of the functions I liked were gone and the thing was slow like I have never seen. Battery drain was big, the phone got scorching hot. Now after 8 years it still does not have all the functions it had when I bought it and it's still too slow to be used even after changing to faster phone a couple of times. And still people are so fast to convert to latest frameworks and do complete rewrites. Most of the time recreating bugs they thought they got rid of many years ago. Or just make loads of new bugs. Or make it so slow on old phones that it can't be used any more.
