/e/'s Bliss Launcher is going to feel more familiar for people who are coming from iOS. For a more traditional Android experience, Lawnchair* would be a better fit. It's just like how GNOME and KDE are closer in design to the desktop environments of macOS and Windows, respectively.
Every Android distribution has to pick a default launcher. /e/ choosing an iOS-like launcher by default is their way of attracting users who want a simpler user experience.

To me it comes off as Apple fans doing Apple-type shit. I'm not an Apple UI fan, but if someone is, they should imitate what they like instead of trying to invent some entirely new garbage paradigm, without any particular inspiration, when they really just wanted to make a nice distro that they would enjoy using.
Having default apps colors aligned is soothing, not sad at all. It's not iOS-y beyond the launcher.
