I was just at a developer conference and was amazed at how many people used Auth0 and OAuth interchangeably. They've done a super job of capturing mindshare, and have a great brand.
More likely those people were somewhat junior. It makes no sense to interchange a vendor with a technology unless the name is literally the same.
Isilon for instance was a brand where there main product was... Isilon clusters.
Possible. I didn't dig into their understanding, but this past week wasn't the first time it has happened.
