Clearly the light bleeding varies across units; some exhibiting significant amount, some just to a minor degree, some with little or no bleed. At the same time, usage of ipads varies; some people regularly use their ipad in ways that moderate light bleed is a real problem, some who rarely/never use it in that manner. Thirdly, there's a variety of responses; some people really don't care if there's some bleed, some feel it's a major disruption to their enjoyment of their ipad.
Mix all three of these together and you simply don't have any single answer to fit all people and all devices.
The trouble with the Internet is that those experiencing significant loss of enjoyment (whether the actual problem is severe, or just the owner's perception of the problem) tend to be far more vocal than those who either don't really care or own ipads that show little to no problems. This potentially gives a false impression of the degree of issues. A secondary effect is it calls to light the potential problem and picky owners go looking for it when they might not have perceived a problem in normal usage.
Net: people should really consider whether the problem truly exists in their usage and whether it makes a real difference in their usage; i.e. does it truly affect them, or is it just that they're bothered by knowing the problem exists on their ipad under "extreme conditions".
