pretty sure hn user timaz != reddit user timaz. I'd bet hn user timaz is the author of the blog post ("Brianna Wu").
I don't really care about the provenance of the work; it's a well-written article on tech in China. If it's a team of a western engineer and a local Chinese person (who happens to be far more attractive/better presenter, probably), I'm fine with that.
I'm ok with the article being presented better, but I do think profiting off it bears ill-will. One of my favourite benefits of the internet is the ability to hide yourself. Pretending to be someone else more attractive and making up a story crosses the line for me.
It's just branding and packaging. If people like buying stuff from a pretty female face, it's not the engineer's sin to satisfy the bias of the customer.
