Yeah, it's important to note that there has been no mention of microtransactions - just the fact that they're thinking about monetization options. It is too early to get riled up over this, but I also think that if there's any chance of influencing the decision-making on that model, it is now while it's still being deliberated, so here are my general thoughts on this.
I can only really judge what CDPR might be thinking in terms of monetization based on their existing MP title (Gwent), which - they've stated in interviews - is a sort of testing ground.
From what I can see, Gwent's model is to take predatory monetization models that exist, and making them slightly less predatory (still predatory, just not to the extreme that the industry has taken those models). E.g. card packs similar to those in Hearthstone, but you get to pick between 3 options for the highest value card, while being less stingy with the rate at which you acquire free currency. I have also seen promotional e-mails for the new card expansions, prompting me to pre-order in order to receive exclusive in-game items - the "CDPR twist" being that they're cosmetic. Mind you, all the while stating multiple times that exclusive in-game content tied to pre-orders is something they don't do.
Now, I don't know about the rest of you, but I believe that CDPR aspires to be an industry leader in terms of being fair to their customers and not trying to milk them for money. My current impression, at least where MP seems to be concerned, is that the goal is to follow the rest of the "industry standards" but only from a bit of a distance, so it doesn't look as bad.
Personally, I would not be happy with that, and I hope their future decisions in this regard are better than the ones they've made so far. I am, however, worried that CDPR may believe that their monetization decisions have been on point so far, since the reception of Gwent's model has been mostly positive. My opinion is that the industry is just so aggressively monetizing games that even something that in reality is "not as bad" is perceived as "good", and that can lead to problems and disappointment down the line.
So, with all of that said, as I mentioned at the start: we still don't how CDPR is going to implement MP and what this monetization they speak of is going to entail, so we can't draw any conclusions just yet, but a dose of healthy scepticism and consctructive feedback based on what we do know is likely not a bad idea.
