Changing for change's sake would mean that Chrome will need a new interface soon in order to not look ancient...
But I mean, you do you man. There's nothing wrong with liking retro interfaces. I once tried to do everything to make my computer look like Windows XP just for nostalgia. Regardless, the product has nice features that would be cool to use, except most people don't want one application on their computer to look like it was there when 9/11 happened while everything else looks new. There would be nothing wrong with having an application with the same features that's not off-putting to most users.
But sure, they can block themselves into a niche of people that don't care if UI looks nice if they really want. That's allowed. Not illegal lol.
You basically repeated my point. Change for change's sake. And it looks similar to 2009 Chrome, so yeah it's quite literally 15 years out of date.
>look like it was there when 9/11 happened while everything else looks new
So change for change's sake it seems.
You can prefer a style, you can customize it to your liking if themes are available (in this case, they are), but if you just replace the whole UI design field with "design is supposed to look nice", what you get might be an aberration. It might be pleasing to some people (but then still some, I really doubt you can find something that is universally pleasant?), but what good is that without being usable? Or if it makes usage much more difficult?
