If you only care about yourself, sure - "just don't buy them" is a good answer. The problem comes when you look at the industry level, at the games that get allowed to be made, and at the people they hurt.
The vast majority of "free to play" games would not be able to make a profit of they didn't find a few players willing to spend huge amounts of money on them. Thousands of dollars, from people who often can't afford to spend thousands of dollars on a hobby.
And not only are these games sustained by such people, they actively seek to find and exploit them, with game mechanics and presentation designed to hook a certain kind of psyche - people with gambling or other mental issues, and children.
