A1260 is not interested in "OS4 purity", as you put it. He attacks anything related to MorphOS (or anything he thinks is related to it). For example anything produced by bplan is "evil by definition" in his books, and he will take any and all opportunities to attack it. He even goes to lenghts to advice against buying Mac Minis (heck, MorphOS runs on it, it MUST be evil!).
It is quite transparent if you take a quick
look at his postings to various threads and newsitems.
Everyone and their uncle Joe has gotten past this childish bickering years ago. I'm pretty sure everyone knows I consider MorphOS superior to OS4 on many levels, but at least I try to stay civil about it.
