The fact that you think this third-party analysis has discovered an incredibly easy way to radically reduce the size of the Facebook app - but that Facebook has not "discovered" the same "fix" - reveals an oversimplified perspective of iOS, app development, and large tech companies.
I absolutely guarantee that this analysis is missing some significant complexities, and that Facebook understands what's actually going on under the hood.
