It's wrong insofar as it's "not X-COM". X-COM isn't about the individual battles, it's about the campaign and the way your soldiers develop over time. In that respect at least it's not Dawn of War - the campaign in games like DoW is a taster for the main game, which is the multiplayer battles; X-COM is almost the exact reverse. Multiplayer X-COM seems to wholly miss the point.
You seem to be seeing this less as a game and more of a statement i.e. "it's not X-COM", "wholly misses the point".
X-COM is a tactical/strategy game. This it the tactical component without the strategic so at best it's missing half the point.
Now if this isn't X-COM then what else isn't the game one might think it is? Basketball is played with fire players per team. If I play four on four is that not basketball? What if it's two on two? What if it's one on one? Half court? Hoop nailed to my garage?
Hockey. Played on ice with a puck. What if I play in the street with a ball?
There are four main varieties of Poker: Straight, Stud, Draw, and Community card poker also known as flop poker. Now which is the one true way to play poker?
You know these sports/games are also usually played as part of a whole season or tournament, but if I play just one game does it not count?
One thing I would agree on is that this game is not X-COM: UFO Defense. It's XCOM Enemy Unknown. UFO Defense already exists, I know because there's a link in my desktop and I'm free to go back to it. I also just bought Master of Orion 1 and 2. I like the first one better but the second has many great features that simply wouldn't work with the other features in the first one. So, call be traitorous but while I want another version of the classic design I wouldn't want to not have what MoO2 is.
I don't know if the developers have more right to say what X-COM is than you do, but they definitely don't have less.
Grappling hooks.
