Yes, you're right that "it can't even stand near in terms of scope", but the original comment did not argue that, the original comment gave an opinion about the usability (actually "to setup/manage", so more like the administrative efforts) of Tailscale, which is not the same thing as the scope of its abilities. Calling the comment misleading because the service has a smaller scope is then at best misunderstanding the original comment, at worst purposefully trying to derail the discussion.
