The wsj article is actually fairly accurate, since it has basically listed all the same arguments.
The question is the last point: assuming everything else here is true, is this sufficient grounds for deplatforming? Do you want to live in a world where it is?
Edit: apparently the HN answer is: yes, we totes do.
Yes, denial of man-made climate change is sufficient grounds for deplatforming in my book. Not that that's happening here. A scientific conference calling for freedom of speech is upset that a scientist is using their freedom of speech in a way the conference doesn't approve of.
Do you want your children to live in a world with +4 degrees because some purely financially motivated people stopped progress on the environmental protection front?
I want my children to live in a world where they are free to think and to read and to listen to a wide variety of opinions, and not just parrot those that come from the loudest voices.
Is the chance of this higher or lower in a world where scientists with opposing views are allowed to deplatform one another instead of applying the scientific method?
The scientific method deplatforms. It is skeptical. It is observational. It is experimental. It refines and eliminates failed hypotheses. It is not fair to all viewpoints.
For example, the scientific method deplatformed geocentrism.
