Reddit tried that before, they bought Alien Blue, and instead of improving it, they turned it into the monstrosity that we now know as the Official Reddit App.

Sometimes, when companies get too big, the C-level executives lose visibility about what the needs of the actual users are and instead, they focus their planning on increasing revenue, no matter what, Quarter after Quarter.

Buying another 3rd party app when they can keep using their shitty app to collect and sell user data to advertisers and marketers without spending more, makes sense to them in their twisted world, sadly.
