Others have already quoted TFA, which rightly points that the distributing (by some of the coauthors) of an article published in the journal of a medical association, at the conference of the said medical association, a conference which has the claimed purpose of exchanging information between the members who attend the conference, can hardly be called a "protest" or a "violation of the code of conduct".

There are few cases where it is so clear cut that only the organizers have violated the code of conduct, and not those who were expelled from the conference.

Yeah this is like pointing out that it’s raining, when it is raining, at a conference about rain, when the only controversial thing is that a massively corrupt administration has announced that there’s no such thing as rain.

If assertions of truth are cast as an anti-government protests, that says a lot about the government.
