Potentially. Though Reddit claims that the vast majority (like 90+%) used the official app. Of course, if such was true then you’d expect they wouldn’t pull the rug out from under everyone.
I can believe a majority used the official up. Maybe even a supermajority. 80% maybe.
But throwing a fit over 1-10% of your user base and doubling down when that low percentage doesn’t agree? I dunno.
It’s a big enough number that made them want to kill the third-party apps but it’s small enough that they felt they could survive the backlash.
