I believe the point they were trying to make is that the naming is confusing for consumers. Even if you’re aware of the difference, the naming is still confusing. If someone with knowledge of the product can’t figure out the naming, then how can anyone else?
The point is, it's not _obvious_. You need to get three pages deep on xbox.com to see the specs side by side.
At a glance the difference between the X and the S could be like the PS4 vs PS4 Slim, or the PS5 and PS5 Digital Edition.
"it's not even obvious which is the more powerful model, there's no mention anywhere of what X and S stand for."
