After reading this article, I still don't quite understand the meaning of technical entitlement. Is it the same thing as technical elitism? Moreover, I feel the whole post is just about elitism - albeit in the tech world - which is nothing new. I don't see the point Tess is trying to make.
I think the buzzword "entitlement" is just being misused here. The post makes more sense if you mentally replace entitlement with a nonsense word like flurblement, and then infer its meaning from context.
