Here's a random example: I think it was like 2017, 2018 when Google launched messages for web. For starters, when it launched, it was located at messages.android.com
I don't think it was much time later before they moved it to messages.google.com, which i think was in line with their SMS's apps like 5th rebranding, this time from Android Messages to Google Messages.
Originally the app had an overall blue theme, and for individual contacts you could change the color of your conversation with them so each chat thread was themed. This even had the neat effect that it would sync with the web version. However, it only lasted like a week maybe before Google completely redesigned Messages to be all white themed, and killed the chat themes entirely so all message threads were now blue and white to look like the iPhone messages app.
That wasn't a rare experience, and I haven't encountered anything like it since switching to an iPhone.
