For the consumers the IPS glow is sometimes not acceptable, and they return their products because of it. But the retailers/manufacturers won't accept the glow as a flaw, as it is an inherent characteristic of the IPS panel technology, itself. Unless there's something VERY wrong with it.
You might want to take a look at
http://tftcentral.co.uk/ reviews. Every review includes viewing angle shots. Although, they only take the shots from one angle at a time (up, down, left, right), they don't take from diagonal angles (upper-right, upper-left, bottom-right, bottom-left). The diagonal angles are indeed usually the worst-case-scenarios and show the flaws most clearly, but (probably) because those angles are not very common in usage, they don't include them.
Actually, if the glow is the only negative aspect on your monitor, then you should consider yourself lucky. There have been loads of threads about backlight bleed in the last couple of years.
In any case, none of the panel techs are perfect:
TN is good for fast-action games, where you need every last millisecond to triumph over your adversaries. But the compromises are usually not worth it for non-professional consumers. And bear in mind, the actual "good" gaming monitors are very costly, as well.
If you're not gaming at all, then VA is a good option, as they have deeper blacks and better contrast. Don't get me wrong, there are still some fair gaming monitors among VAs, as well. But indeed, VA is usually not hailed for its gaming prowess. It's a good all-arounder, and in some cases I would even recommend VA over IPS.
But in the end, IPS is still the optimal choice for most people. Especially after the prices came down few years ago. The benefits are simply greater than the compromises.
Low price, high quality, selection of features. When you focus on one, you'll have to compromise on another.

You do know that the thread you referred to points back to OcUK? Here's the linked thread:

Didn't read it through (27 pages!), but from the looks of it, the primary issue with that monitor is indeed the backlight bleed (BLB), which has been on the focal point on many of the recent feature-rich monitors.
