Yes, it is a decade old. Back then it was called "Oasis". Here's what it looked like in 2013 if you'll excuse the custom social media code - not much different. Here's Halopedia before the change, and then Halo Nation after. Probably not the best example since Halopedia and Halo Nation were big with customisation (to the extent the software Wikia got rid of in 2010 just appears as rich text to me).

Point is - this software is old, and people even back then complained about it ruining their experience. Then Wikia finally patched it and people got used to the new normal.

I assume you weren't around until the time Discussions came out, so wouldn't be familiar with 2010, but it is a clear example of people complaining about software changes.
