Netflix was the first SV company to articulate all these ideas (more or less) coherently. They are now pretty common, especially the no-specific-PTO policy.

This is kind of like the "Seinfeld isn't funny" trope.

You may or may not agree with their approach (and apparently it has changed a bit from when it was written - including the head of HR who pushed these ideas being semi-forced out!) but Netflix should get a bunch of credit for innovating on corporate culture.
