Indeed, personalities don't matter. To make an analogy, there are scientists whose personalities, and even political views, turn me off. But what matters is whether they do credible science.

If it's just somebody's hobby to release information, than that's as far as it goes. But in order for the information to be actionable, it requires interpretation, and then the process of choosing what information to release becomes important.

Imagine how a hypothetical scientist's results would be interpreted if it were known that they were only publishing the information that favored their own agenda -- personal, political, commercial, etc. Yet none of the data points that they publish can be discredited.
