HN isn't the source though. the two articles I can remember are sfgate.com, readership in around 30 millon/month, and ars Technica, which is a fairly popular site, though I don't have stats for them.
That still doesn't sound a terrible situation for door dash considering the global reach. Not sure about sfgate, but ars would be a pretty niche group as well
It was reported today on local TV news here in NYC (NY1), which is what got me to search HN for this discussion.
And since local TV news isn't exactly geared toward the tech savvy, I'd expect this will be widely covered across US media.
