The solution of solving your app branding problem by renaming the less used apps with the name of the most widely used app is something straight out of the Onion.
How many of these "10x more installs" are due to Duo coming preinstalled by default on Android, which AFAIK isn't the case for Meet? A quick look at two Android phones I have nearby showed both have Duo installed (and never opened), while none have Meet.
Last I checked it was quite popular in Asia.
I think of Duo as "one of the google apps I will never open" whereas I have meetings in Meet. I guess I figured that Meet got a pandemic bump? But when you put it that was it does indeed make even less sense.
