Respectfully, I think you’re generalizing a lot based on your own opinion.
I don’t particularly need advanced z-wave diagnostic tools, and although there are certainly some value-added services I would consider paying for if hubitat were to offer that, detailed hub troubleshooting and/or performance measurement tools is not one of those things I would pay for.
This isn’t really any different than the most recent “performance edition” hub discussion thread, as a few others have pointed out already.
@bravenel’s response in that thread was pretty consistent with several other prior threads, in which he points out that many of these advanced feature requests would serve a very small minority of their users (albeit a very vocal minority).
