If you argue this is bad behavior: Maybe we need a web query which really only takes the query literally. Putting the query in quotes will not quite have this effect for Google. Maybe some other syntax?
In this very specific case I don't buy it. Sure, it probably applies for other queries, but if you approach a salesperson and ask him for "shirts without stripes" it's pretty clear what you want, and he wont bring you any piece with stripes on it.
The only difference is that those are all physical properties of a shirt while stripes is a type of pattern.
See how that works? That's not really what's going on. Sure, G. is incentivized to include pages quickly, but they are also incentivized to produce them accurately, and as the above poster indicates, this is quite a hard problem to solve generally.
A is also incentivized to sell items.
In many cases different algorithms will lead to quantifiably different results. The algorithm changes that work better for the measurement set will be kept and those changes which dont will be discarded. And both A and G do that within different constraints.
Pointing out the obvious: Google is an advertising company. If the cost of producing an accurate result outweighs the advertising income on a given term, there is no incentive for Google to produce better results.
