Mike does not develop Amiga software right now.
And? Trevor himself doesn't program any software either. The comparison was that someone can indeed "waste" spare time and/or money for some hobby when his real job earns him enough money to do so. And as far as I know Mike did not state yet he does his C-A Acquisition endeavor for a living.
Please note: I don't claim the opposite either. I just considered it funny to totally rule out Mike could do this out of enthusiasm only while there's Trevor at the same time going around for several years now spending his money here and there.
