Google has recently screwed this up too with Material You where every single icon looks basically the same. App icons should be distinct. They are there for you to recognize the app! Monochrome and uniform shape does not help with this.
This does have an upside. Sort of. People are more accepting of dark patterns, as when you have to mouse over the ad before the "x" to make it go away appears. In a different place each time, for the worst cases.
If you're drawing shapes, why the fuck do you intentionally break them? Shape-breaking is the exact thing animal and military camouflage do to make animals and humans less recognizable in the environment. And Google applies it to something they want to be spottable.
@mcclure111 used a colorblind filter on them and they look better, as expected, because the shapes get broken less.
Google basically failed Design 101.
My brain basically chooses icons by color content, so when everything is a primary color picker, I err frequently.
Im at the point that if something gets annoying I simply drop off. If ads for example become unavoidable Id stop consuming, %99 is utter waste of time anyway. End of rant
