It doesn't have to be third party to be considered bloatware. The OP was specifically referring to the Apple Watch app. There are plenty of 1st party apps on iOS devices that many consider bloat (Stocks, Voice Memo, Newsstand, Tips, etc). Android is subject to exactly the same criticisms--for instance I believe the post that you quoted was inferring about the inclusion of Google+. And while yes, the Nexus isn't subjected to the most commonly referred to bloatware (OEM or Carrier specific apps), the overwhelming majority of Android devices do have it.
