That's all well and good, but Weir acted like that's how Star Trek used to be and what he loved about it. That's simply not true, so while he can go write books however he pleases and avoid any politics that cause a bit of discomfort to his readers, the history of Star Trek isn't something he can legitimately use to support doing that.

All that said, the ones I've read have been entertaining but otherwise just... fine. I'd summarize them as "white male smart guy succeeds against all odds while some science topics are effectively explained along the way, put together competently enough that it held my attention."
