There it is. There is a coordinated ploy by the industry to sell more expensive hardware: shitty software. I find it hard to believe that such simple multitasking (using compute-intensive software + watching videos) could cause a well-built desktop computer to slow down.
Since there is no alternative to inefficient software, products such as the 2019 iPad are praised because they can bludgeon through these tasks and still appear fast, but only due to their sheer power.
It's disgusting, honestly. Apple pushes iOS so much because that's where they have almost full control over software, and therefore they have full control over your device's perceived performance. This isn't even limited to Apple. Case in point, https://mail.google.com
What are we, responsible computer enthusiasts, to do about this?
