Hey @matthew_wheeler, there was a lot of confusion as to why Helvetica Neue didn’t work on non-OSX machines (it’s only installed on Macs by default), so we decided to remove it because it’s not a websafe font (and because it’s not available on Google or Typekit web font foundries). Sorry about that!
What browsers are you targeting for the sites you create? Are you OK with Helvetica Neue showing up as Arial on Windows machines? (Keep in mind that Windows users make up significantly more than half of all web traffic.)
