Irony
Of course, none of those technically have any impact on whether it's an "RPG" or not. 
They are your preferences, however, and are therefore a valid means of deciding whether you want to play a game or not.

Personally, I'm enjoying the game. And the whole definition of "RPG" has always been somewhat vague when applied to non-tabletop games (since you can't really roleplay all that well without a GM who can react to your decisions and modify the game/plot/story on the fly). JRPGs and ARPGs, for instance (as well as the oldest pre-Baldur's Gate D&D games) are much more linear (with generally no "choice" outside of picking class & skills, and no narrative variation or consequence). Are they RPGs? How about action games like the Zelda games? Are they RPGs? I've seen people over the decades argue all of those.
By the general standards of the uber-roleplayers on these forums, at least 90% of the RPGs released over the past 30 years weren't RPGs. Doesn't seem worth it to get worked up about it.
There could definitely be a bit more choice & variation in conversations, that's true. Seems to be more an issue with their wanting to have dialogue chosen by up/down/left/right(or d-pad), rather than anything inherent to "dialogue wheels" or voiced protagonists (see Bioware games, that have plenty of options, on a wheel, with a voice.)
