The step from "If people want to spend $18 for in-game paint sets or something, I say go for it." to "If people want to spend $18 for 10% more damage, I say go for it." is small. Another direction is meaningful contect cut out and sold later as micro-transaction. Imagine Pathfinder:Kingmaker where in the base version you only have Fighter, Rogue and Wizard classes. Each additional class costs $5. At the latest when this happens you will care?
However there's nothing you (or any other single person) can do against this trend.
So the end result of just ignoring stuff like this is the same as in your approach. The difference might be a casual rant here and there.
