Can't read the whole thing because paywall.

I thought nature was about publishing research. This reads like a political opinion piece but is published as "news"?

The author has other similar articles like these about the "US brain drain":

What would help me get an accurate picture is how many conferences are typically held per month in the US and how has that number changed but instead we get fluff like:

"Some meetings have been put on hold" - which meetings?

"Several academic and scientific conferences in the United States have been postponed, cancelled or moved elsewhere" - Which conferences, what % of the total? more specifics?

"Organizers of these meetings say that tougher rules around visas and border control — alongside other policies introduced by US President Donald Trump’s administration — are discouraging international scholars from attending events on US soil. In response, they are moving the conferences to countries such as Canada, in a bid to boost attendance." - Which organizers?

EDIT: I found this resource which would be interesting to examine for trends: https://conferenceindex.org/conferences/science

EDIT2: there are some specific anecdotal examples towards the bottom of the paywalled article. This is still not meeting what I would consider accurate non-opinionated reporting.
