The author is anti Wayland
The authors' point of view does not matter. You've poisoned the well by presenting the data collected as potentially "tainted" by a bias that, even if true, does not change the data presented.
So yes - clearly and very obviously poisoning the well. Textbook really.
Why don't you do that?
The link you provided actually did that. But they are "anti-wayland"...
Edit: and I'll push back hard on the "anti-wayland" language as well. This is propaganda-style speech. People can "not like things" and disagree. But labeling somebody "anti-x" diminishes their opinions and ideas.
