Non-competition for what???

The blog author is the developer of the mGBA emulator which is free and open source... There is no commercial competition for Analogue there.

In the sense that no one else is making money off of it, sure, but it is a factor which could impact their sales.

This whole thing sounds more to me like one of Analogue's lawyers thought up a scheme to lock down that project for cheap under the guise of paying for some development work.
