This article seems to be underestimating how much RAM a weather app should take. A well thought-out, native Weather app wouldn't take more than 100 mb of RAM.
This has strong "How much could a banana cost? 10 dollars?" vibes.
Back in my day 100MB was all you had for all your compute, and somehow programs still ran.
My favorite '90s weather app was WetSock. The installer was 1.5MB, though I don't recall the RAM usage. It showed a sunny/cloudy/etc. icon in the system tray, with the temperature in a tooltip:

You don't need anything more than https://wttr.in/ even with all the fancy terminal graphics.
Well it's comparing it to apple's weather app, which is a fair comparison I suppose. 100mb still sounds like at least an order of magnitude too high to me though.
What is the weather app doing that it requires 100MB? For such a simple application, that seems excessive.
