Lots of sore fake libertarians who labelled themselves that way only because it made them feel important and gave them an excuse to get a fake job at a foundation. Now that they see someone actually doing something they know they have been all exposed as posers whose sole purpose in life was to keep cashing in donors money "for the cause" (of endless fancy gatherings and fancy platitudes disguised as sophisticated articles). They now must prove Milei wrong at everything otherwise they will be regarded as the useless posers they are.

Clearly insufficient awareness of the available data by the author. Beyond that, it's likely just that none of the editors knew enough about the situation to catch the oversights.

It would definitely serve them well to run these past someone with first hand knowledge to avoid such embarrassing publications.
