IMO, this is 2 issues; what Lowell said in the video, and what Prof Dave has said afterwards. I thought what Lowell had to say was much too personal. Especially so considering it was said publicly, and it was directed at his former Safire team members. That old saying "praise in public, criticize in private" comes to mind.
Had he stuck to the science, that would have been fine as that is what science is all about. But he went beyond that and made it personal with insults that called into question the professionalism, and integrity of his old friends. No need for that.
Anyone who has worked in, or headed up a team, knows that personality clashes are par for the course. That is as true in business, as in science. It is the nature of the beast when you bring people together to accomplish a task. Some people though, just do not work well with others, and that seems to be the case here.
What this Prof Dave has had to say since the video, in response to the criticisms, is not making matters any better. He comes across as petulant, and because he has backed himself into a corner by saying some regretful things, and resorting to censoring to give himself the edge, he seems to think his way out is to be more insulting, and petulant.
The Aureon Energy group has decided to do the right thing...take the high road. They will not get in a public spat with a bitter former colleague. And contrary to the ad hominems in the video, they are a very well qualified team, and have only good intent. They are all well up in the years, and each without a blemish to their credentials....that alone tells you what you need to know about their integrity. Their high level of science/engineering speaks for itself.
