You do not believe it is merely a possibility/possible scenario, you think it will happen based on what you keep saying; in your mind you have already made the jump from possibility to certainty. There is a difference. Someone who considers the future as a job or career should know better than that. You have a closed mind on this and forward thinking people in general should not.
If indeed you was a forward thinking person and considered the possibilities you would have said it is possible they might change their mind about vanity only items switching to P2W items too based on what other developers have done but you ruled out all possibilities with exception of the most negative one then jumped on that bandwagon prematurely and prior to it happening by deciding in your mind it will happen despite being nothing more than a possibility...one that is not based on what SE have done but what others have done instead.
