Chill, it's not that big a deal. You're making an issue over semantics.
Derpibooru has been using the "Pinkamena Diane Pie" tag for this version/mode of hers for many years. Pinkie Pie went "Pinkamena" 6 times (that I know of).
1st - Party of One
2nd - comic series when the Mane 6 went up against Chrysalis; Changelings imitated others and made fun of her
3rd - In the novel by G. M. Berrow, she gives up being a party pony to help her family and asks to not be called "Pinkie Pie" anymore but "Pinkamena"
4th - Cutie mark switch-up in Magical Mystery Cure
5th - Comics again when believed to make ponies sick with her sweets, called herself a villain
6th - Yakity-Sax
.
It's also referred to her in the alternate Sombraverse arc.
Each time she loses her inherent identity, by decision or influence, and reverts to the demeanor and attitude, or worse, of herself before parties.
There is really no reason to be upset; you have a whole bunch of canonical foundations to justify calling it going "full Pinkamena". She's been sad before but this is clearly something different, if not a state of personality disorder like Bipolar.
