This is a big one that makes low-bandwidth connections unusable in a lot of apps. The deluge of ad/tracking/telemetry SDKs' requests all being fired in parallel with the main business-logic requests makes them all saturate the slow pipe and usually leads to all of them timing out. By being third-party SDKs they may not even give you control of the underlying network requests nor the ability to buffer/delay/cache those requests.
One advantage of being Facebook in this case is that they're the masters of spyware and are unlikely to need to embed third-party spyware, so they can blend tracking/telemetry traffic within their business logic traffic and apply prioritization, including buffering any telemetry and sending it during less critical times.
