1. The CEOs insistence on "Competition" as the cause for the increased focus on short term impression rates seems pointed at regulators and Congress rather than at investors. This is silly too, Google had no such pressure on impressions and performed rather well just days before.
2. The cat is out of the bag. Facebooks secret sauce was their very HEAVY focus on bottom funnel advertising where they would ascribe suspect numbers that were not Industry standard to "Conversion" objectives (RoAS anyone?). Anyone, anywhere sees an ad at any point in their conversion journey and Facebook would assign a large weighted portion of conversions leading from that individual in their reporting.
3. The big scary underlined headline here should be HOW POWERFUL APPLE IS. They sneeze and change one small thing in the way apps can access their platforms and we see an entire industry shaken.
4. They won't die out quick. These numbers, though not "Growing" as fast as befor or expected to grow as fast (which is the bigger concern), still is much, much , much higher than they need to sustain their business over the next two decades. The big risk though, is the stock price drop which is how the bulk of their pricy talent is paid dropping. Everyone there is currently staring at a 25% pay cut on their stock based comp and that is not a pretty picture for attracting the best kids graduating this year with ambitions of joining a fast growing tech firm or pulling in talent from places like MSFT or GOOG or AAPL who will not want to jump aboard a perceived sinking ship.
