He's approaching this as a simple restructure & pray with engineering teams when in fact the problem is a much more serious problem, there's a loss of confidence in Twitter from investors.

1) Investors realize twitter is horrible for monetization
2) Investors are out of patience or trust
3) Twitter scrambles to find a sustainable revenue source.
4) Twitter cuts off Hootsuite and launches competing business
5) Twitter's massive botnets disappear revealing only a small number of it's userbase is active sparking SEC involvement.
