Don’t forget the OG offender in this category, the PSOne / PSX
In Sony's defense, everything else with the PlayStation was actually pretty straightforward. PS1, PS2, PS3, PS4, and PS5.
"PSOne" was a weird way to brand a slim console, but it's still obvious that it's a PS1. And while Sony did originally use PSX to refer to the PS1, that was an internal codename, i.e. "different from the Nintendo PlayStation[0]". The gaming press ran with it because people in that era insisted on awkward three-letter acronyms for all games consoles. Reusing it for a weird PS2 DVR combo unit is still way better than Microsoft launching two different consoles with the same name.

The One/Series S/X crap is genuinely baffling, totally incomprehensible unless you've really been keeping up with every Xbox release. You can go on Wikipedia and figure it out in a few minutes, but...you should not have to do that.
