I don't think the PR reviewer is calling the author a liar. The reviewer said FreeBSD is not willing to lie to its users about version, and instead provided useful info, pointing out the relevant example.

Still, there's a lesson for reviewers that tone is important, especially over text and where a power differential exists.

Also, the author notes:

> The very first comment in the thread from a reviewer was simply only one word: “Why?” - That’s it, just one word. Why did I do this? Why work with such old hardware? Why is the sky blue? How the hell am I to know the context of what they’re referring to when asking a one-worded question?

Its clear from https://github.com/freebsd/freebsd-ports/pull/189#discussion... that the author is asking why is this line needed, something a PR author should always be able to justify.
