The author assumes that all EVs behave like Teslas. Other car manufacturers are aiming for simpler UI, and the charging system itself is meant to deal with the oddities of deciding exactly how much to charge the car to. For instance the often don't show a charge percentage but an estimated range with bounds.
I apologize for not bringing a link but there is a beautiful story of real world range that shows that Teslas are systematically over reporting their range. It was posted recently. The author should probably read it before generalizing...

It's not a Tesla thing, it's just battery chemistry. Virtually all EVs are being sold with NMC batteries which don't like sitting at 100%. We're starting to see a few LiFePO4 cars arrive on the market, which is a heavier but much more durable chemistry. Most of those are BYD cars, with a few other Chinese brands.
Ironically the most common iron phosphate car to be seen on western roads is... a batch of chinese-made Tesla Model 3 RWD's that reached the US market last year.
It doesn't matter if the 80/90% charging is hidden in the UI or not. The EPA uses a 100% -> 0% range, and all vendors use this range in their marketing material.Of course they do, because people compare product sheets when choosing.
The actual range you will use day-to-day is way less. That's what I wanted to point out.
Many Teslas being produced today use lithium-iron phosphate batteries, which can be charged to 100% without degradation. If you have an LFP-based Tesla, you won't get the notification.
