Microtransactions are everywhere and it doesn't matter if you're playing a mobile-, indie- or AAA-game. The possibility to spend money is even within full priced game titles. Be it convenience, cosmetics or even raw power. If there is a way to make you pay it will be used.
Some games, like the newly released Diablo Immortal by Activison-Blizzard, are so overly predatory that your willpower is under constant attack by all the tricks that the industry can come up with.
Allthough free to play games need to generate some money, which is understandable, it is the highly predatory shop-mechanics that hit the news nearly constantly.
You will also find players who say a phrase like "Well, you don't have to pay anything. Just enjoy it as much as you can and then move on". This phrase is within the realm of blissful ignorance because the moment you are within the game your willpower is attacked by a constant reminder that you can burn (just a little) cash to get "super awesome stuff".
