"Why so many brands change their logos and look like everybody else".

In the past year(s) I have noticed a few icons in my Android phone turning into the same thing.

For a long time there was Uber, white on black. And then others thought white on black was the cool thing to join in on, making the reduced icons of the following look the same : Uber, Soundcloud (they kept their sigil at least), Swile, Qobuz, myNoise. I'm sure if I installed more junk I'd have seen more.

Even myNoise who goes against tech grain! To their credit, they added an orange circle background to it sometime this spring. Soundcloud execs woke up and went back to their trademark orange. But, heck.
