If what this article is saying is true, then I somehow feel the iPad OS instead of being efficient and modern, is actually a bloatware and memory hog. I mean, I can do multi tasking with multiple windows on 4gb ram 13inch macbook pro released in mid 2012, with no problem, i'm not joking, i used it during the lockdown time 2020. But if a modern iPad OS with a modern chips like a A12Z cant handle multi tasking then i feel something is wrong somewhere.
