I'm impressed that Cory Doctorow's (@pluralistic) critiques of late-stage capitalism have made their way in the minds of so many disparate people.
Here is a #bike YouTuber noticing the shift in value delivery from customers to shareholders & calling it enshittification. Might not be an exact match for the platform/intermediary model of Cory's that specifically calls out middlemen who deliver almost no inherent value, but still it is a significant spread of the concepts.
