This situation is typical of much of Adobe's modus operandi for software: pack the applications so full of features and turn the majority of them on by default such that the application comes to be regarded as bloated and slow. It's little wonder that Adobe Updater is always interrupting workflows when it has to check for the kitchen sink and then some.
It's a good thing that rich PDFs have not taken off like Adobe hopes they will, otherwise instead of a minor annoyance it could be show-stopping.
Hopefully the company will be able to update all affected products and make the correct design changes now while the problem is still small.
In the meantime, I'm sure Foxit Reader will enjoy all its new users and OS X/Linux users will be thankful for built-in readers that are typically "good enough".
