The actual title is "Companies! Don’t discriminate Front-end Developers!", which changes the headline meaning in my opinion[1].
As it is, "Companies Don’t Discriminate Front-End Developers", sounds like the crux of the Medium post is "Companies do not discriminate against front-end developers", whereas, the post headline and content reads as, "Companies, stop discriminating against front-end developers."
While its more of a rant, it would be nice to have more specifics on that complexity vs UX and other generalized subjects.
I say this, because being submitted to HN it is probably targeting a technical audience, vs, this reads more to "business" folks who may not understand the back end vs front-end.
[1] Maybe HN removes ! marks, so I would edit in a , if possible after "Companies".
