Edit: Looks like you can opt-out of that "new look and feel" pretty easily under the appearance settings but still, whats with putting rounded corners everywhere?
Edit 2: "Explore the web with a softer, more friendly aesthetic featuring rounded corners […] Designed to complement your operating system, whether on Windows 11, MacOS, or Linux." The fuck does that mean? Windows 11 fair enough but most Linux distros don't look like that at all.
As it’s Microsoft, you can be pretty sure the option to turn off the new look and feel will be removed in 6 months
Or half finished and left in there for decades
It could even be both, if you really think about it
