Apologies, but none of that context came through in the two sentences of your original quote. The subcontext (why not more widespread) you've created is even less clear. Class actions are almost always local. It's rare to find one that goes national or even regional. Besides, I don't think anyone classified this as a big problem... because it wasn't imo. Remember, Apple's sales numbers on the 4 and 4S at that time weren't stratospheric like today's iPhone sales.
I personally think it only gained real interest because of the apparent smoking gun email trail that allegedly supported the idea that Apple crippled iOS6 to avoid paying large sums of money to Akamai. That email trail is one of the primary reasons I think Apple settled. Going to trial could have led to more damaging discovery.
Patently Apple had a nice detailing. I used the link to the Florida case since it contained the same info. Excerpt:
"
Hey, guys. I'm looking at the Akamai contract for next year. I understand we did something in April around iOS 6 to reduce relay utilization," Apple engineering manager Patrick Gates said in an email to employees. The message was met with a response from engineer Gokul Thirumalai, who said, "It was a big user of relay bandwidth. We broke iOS 6, and the only way to get FaceTime working again is to upgrade to iOS 7."
