Popularity or usage isn't the same as merit. Redesigns of apps may be absolutely amazing and objectively better but that doesn't mean they will see a lot of adoption. People don't automatically adopt things that are better. People flock to apps or interfaces like birds. That behavior doesn't tell you which things are better.

Of course, you can do a good UX design and good graphic design (both together, but they are two different aspects) and then use psychology and network effects to your advantage. Or just switch interfaces on a certain part of the users and then the rest may be jealous. Or other tricks.

Marketers want you to believe something fancy and trendy and expensive is better and so people want that status. That isn't the same as being actually better.
