You might be right (though there may be other explanations, e.g. ageism or just wanting local employees, and writing "remote" just for the heck of it, "to get more leads"). But even if you're right, that just reinforces my point: I'm not desperate to get a job; I wrote to have a discussion, because they managed to pique my interest... I didn't put any kind of effort to "market" myself, thought they'll figure things out in the interview(s). They were basically fortunate that their advertising hit he right target. And what did they do with that lead that they got? They throw it away through a non-technical filter....
