Unity have already established market dominance, if not effective monopoly, as the mobile gaming development platform. They are in a position of power, they have invested large sums of money to get there, and there is really very little game developers with a product 1 or 2 years in development can do about it.

While this is going to be difficult for Indy developers, they really only have themselves to blame. Part of the task when you are making a major software platform decision as a company is to research your vendor’s financial strategy - that’s basic due diligence. Unity has been loss making for years, which either means they are not financially viable (and not a safe bet), or they are engaging in a strategy of establishing an effective monopoly position to later squeeze dependant customers until the pips squeak.

This is likely just the start, whether it’s through runtime charges, Unity control of in-game advertising, or huge hikes in seat license fees. Possibly all three.
