It is actually possible to design lids that are easier to open. See for example here: https://metalpackagingemea.sonoco.com/our-orbit-closure/
I already tried a jar that had one of those lids linked above. It was indeed a lot easier to open.
The way that it works is that the lid consists of two parts. The flat upper part presses against the sealant surface and doesn’t turn. The ring shaped part on the side that grips into the threads of the jar does turn. The fact that you only have to overcome the friction in the threads and at the point where the two parts of the lid meet but not the friction at the sealant surface means that it is a lot easier to turn.
So yes, when someone notices and cares, it is possible to design stuff that is usable by almost everyone and not just by half the population.
This additional info was very helpful to understand your view. Maybe you could have included it earlier and not just in your second reply. I first thought you were just pissed that Holly criticizes you when in fact your problem with her is the hurtful and unfair way in which she communicates those criticisms.
I get the impression from your first reply that you think that this is immediately obvious when one looks at her twitter profile. To me, it wasn’t. And @Caleb Biddulph’s reply looks to me like it also wasn’t obvious to Caleb.
