The irony of this is that some influencers in the BTC space are dubiously accusing the current president of suppressing dissent and criticism just like Castellanos's, as if he's threatening El Salvador's "oh so thriving liberal democracy."

Considering such a specific topic, I bet most influencers are poorly informed about it.
