I think there's a point where it feels like it's gone beyond simple price discrimination to leveraging hundreds of employees and millions of dollars to actively manipulate and exploit a player base that is often substantially comprised of children. I've watched developer presentations on how best to implement Skinner boxes and other gambling mechanics to help condition users and obscure exactly how much they are spending. That may be fair to judge a company poorly for.
For me personally, it represents the fact that the company is actively working against my best interests, and that feels bad. Additionally, completely selfishly, it makes me sad to see games that I would otherwise enjoy be distorted by this sort of monetization.
