In a blog post, Validas concludes that throttling isn't being put in place to curb greedy data hogs, but rather to migrate users of traditional unlimited plans to tiered plans. These plans are far easier for AT&T to manage and don't pose threats to its network.
If AT&T can produce an independent, third-party study that proves its throttling measures target only a minority of bandwidth-sucking users, the case would be effectively closed. If it can't, it should stop throttling unlimited-plan users who use under 4GB of data per month, or introduce something equivalent to the transparent throttling that T-Mobile has established for customers who use over 5GB per month. Standard business-only usage, such as email and the transmission of most graphic files, is not going to add up to the average numbers that unlimited data-plan users are polling with Validas.
