The comment I was referring to also used the phrase "2 ton death machine" instead of calling them cars. That's usually a good sign that what a person is advocating for is more than merely adding more non-car transportation. :-)
And indeed, checking their other comments they also want to greatly reduce parking spaces for cars in cities. That would make it so most people in cities could not own cars, and greatly raise the cost of parking for those that do own cars meaning cars could probably be owned by people in the top income groups.
So I think my inference that the type of city they are advocating would be one where data center employees would very likely not have cars, and so data centers would not be in the middle of nowhere.
