Yep, this 100%. I worked on Facebook iOS app perf/reliability/efficiency for a couple of years. The company is structurally and politically incapable of making a lean app (thousands of engineers have their performance reviews tied to launching new features, not deleting old ones). So they rely on a relatively small number of engineers making heroic technical fixes in order to make it possible for the app to even boot. Similar situation on Android. The status quo is clearly dysfunctional but I would be surprised if the company ever figures out how to fix it.
