The topic of this thread needs to be changed to "An immature, open rant about Dave Haynie" since you're too stubborn to actually contact him yourself. It isn't like he's trying to hide from you. Why are you making this so personal and airing such dirty laundry in the open? The reasonable thing to do would be to contact him personally and settle your differences with him one-on-one instead of turning this site into your own little "I hate Dave" site. Stop trying to drag MOS fans and the uninformed into your little mud-slinging tirade.
As much as I don't enjoy seeing threads like this one, I think you are reading too much into it. The accusations levelled against the MorphOS developers were made in the open, I see no reason why the accused shouldn't be able to challenge the claim in the open too. Furthermore, there's nothing particularly "ranty" about the opening post. It's terse and to the point, sure but nothing that could be construed as a personal attack in the forum TOS, as far as I can see.
While some comments in this thread intimate the view that he's an irrelevant has-been with nothing better to do than criticise everything post commodore, I still have a great deal of respect for Dave (besides, better to be a "has been" than a "was nobody"). Even if he totally hates MorphOS, OS4, AROS that's fine (everybody is entitled to their opinion), but making accusations without being prepared to back them up is a low blow in my opinion.
Piru obviously has a lot of time and effort invested in MorphOS and in his shoes I'd want to see some evidence to a claim like this.
