They do. While I do agree that the E175 is not a bad ride overall in Y and F compared to the rest of the UA narrowbody fleet (excluding the 752), the lack of hot food is really noticeable once you experience breakfast on an AC E175 that isn’t a dreadful cheese plate and is better than most of UA’s mainline breakfasts.

As for the plugs not fitting - I have noticed that and find it supremely annoying. Why they chose to have the power outlet installed at an odd angle undoubtedly has to do with costs, if I were being cynical...
