You're right. But I don't think the chosen model is going to flourish too.(personal impression based on most users reactions)I, personally, don't think Game Maker has, or will ever have at the current trajectory, the same situation.
In addition to leaving users, soon it is also quite probable that the guys in love of cracking softwares would start their job again. Why not? Imagine GM is completely cracked with all features active and free export, without the need for paying a single penny. That would definitely cut off the income of GM considerably.
