Except from the "political" part of the definition, which everyone understands from the current context that this does not apply, what part do you disagree with?
You are saying "everything works amazingly well". Others are reporting "simple things don't work, sometimes it just segfaults". Of course those other people can perceive your post as a form of propaganda.
I have never used Wayland (I don't have a good reason to try it), so I don't know whether you or GP is correct. But there is obviously a possibility that GP is correct. You could even both be correct, if there are hardware-related bugs that you just happen to not experience.
You just accused me of writing up "information, especially of a biased or misleading nature, used to promote a political cause or point of view".
