Yeah, I agree with @Gray Ghost.
Firstly, if C is for "computer," then every single RPG that we're talking about is a CRPG, in which case what's the point of adding in that extra letter? It is entirely redundant. Secondly, the language does matter because otherwise we're all just talking in isolation here. We can have conversations with each other, and especially engage in comparisons, only if we have a common understanding of our language being used.
And finally, I also would question how DA:O is not a cRPG (where the C is classic or old-school) but BG3 is? Sorry, but that just doesn't make any sense to me. DA:O is far more close to old-school RPGs than BG3. And if anything, for me, BG3 is more closer to DA:I and Fallout 4. The whole point of BG3 is to be a very modern game, complete with all the modern crap that today's gamers apparently demand in their game at the expense of the things that were at the heart of old-school RPGs. BG3 is no cRPG.
