i think the issue is that this new player was released and it was never disclosed (initially) that it did not have a GUI that was the same as all the other recent players. It's GUI was 1080p instead of 4K. Had it been disclosed in all the original materials that it had a significant change from the other recent Strato players, then of course no one would have a right to criticize the company for the features it chose to put into it.
But many users thought they were buying an "upgrade" to the Strato C because of the new DolbyVision capability, and they found out that the GUI was lower, which was a surprise. I personally don't think it's a huge deal (I bought a V), but I don't criticize users here for expressing their disappointment given that the change was not included in the specs.
Certainly doesn't warrant your calling people here "petty and entitled" for expressing their opinion on the matter.
Since you use Apple as an example... what if the new iPhone 16 was released with a lot of fanfare, and description of its capabilities, and people bought it and THEN found out that it could only support, say, wifi 4, not wifi 5+6 like the iPhone 15 does - a downgrade that was never disclosed to the early buyers. Some buyers may never notice, some may not care much, but if someone did expect their new phone to be have at least the capabilities of their old one, with no info from Apple about this, would you call those buyers "petty" for raising the issue and wondering why Apple never disclosed this change?
