Everyone has some sort of stance. There's nothing wrong with that. What is wrong is masquerading as "news" while pushing your world view. Creating a narrative and manipulating the reader's emotion is not reporting news. If you have a position as a journalist the honest thing is also to disclose that position.
News should be objective or as objective as possible. This is what happened. Report on that. This article could have been rewritten along those lines/principles:
- Report/lead with what actually happened. (these conferences/these dates/information about the conferences/their decisions)
- You can interview the organizers and quote them.
- Ideally you give a broader context (e.g. yearly we have 10k meetings/conferences and these 4 have been cancelled) even if it doesn't support your narrative because that's what an educated reader needs to have to be able to form their own opionions.
An analysis is not "news". If you're analyzing some trends then make clear that's what you're doing. An opinion is also not news.
