Neatly attacks the corporate/government assets
Thankfully IE's usage is dying on its backside, my logs are showing it at 24% and falling each month.
The problem is that big corporates and governments still use IE because of their standard builds, based upon Win XP and glacial slow update cycles. These environments rarely allow modern browsers, so IE usage on these estates will be 100%. This is a gift for the bad guys who can exploit IE with impunity. Once Microsoft patches this hole, it just leaves the rest of the IE sieve to patch.
It's really a failure of the IT department governance. But they're driven by policy, which is developed by the organisation which is run by people who've no idea what IT is... Such a sad state of affairs.
