I also have no problem with him selling his stuff.
For example, Malectrics (the first link) both sells his design as kit or finished product. But he also release all the schematics/PCBs on github :
Some other only sell their desigh (like the JP spot welder on endless sphere). That is absolutely fine.
So please calm down. Your definition of “not selling” and “sharing” is quite a personnal one, that’s all.
I have nothing against him, quite the contrary, I find his stuff great !
