You all seem to be in agreement that Google can't tell the difference between a $100 account and a $1,000,000 account. That is an insane business model if that is correct.

So those that spend $10 at a grocery store get kicked, while those that spend $100 get "Thank you, come again" on the exit?

amount of money

I believe that Google is in a very specific situation, opposed to any other XYZ business that cannot afford to lose customers that spend a lot onto its services.

If XYZ denies 1,000 or 10,000 customers that spend 10M or even 100M a year in total, that would probably be the same amount accounted for being "short" in their earnings which would cause huge trouble from many perspectives.

If Google denies same number of customers, it does not lose anything (or much) as the competition continues, and gaps are filled with other active advertisers. Showing 14 or 15 ads at the time does not make much of the difference in regards of the price for top positions, nor how many clicks happen per one search.
If the given search result goes from 15 down to 14 ads showing, any single ad will have a chance of getting more clicks since the 15th is gone.

Google AdWords has its own CTR which is the ratio between total number of searches for a single term and clicks onto paid (all ads) vs. organic results.

Google AdWords' system is better then any other money making machine known today. It is backed by patents which are publicly announced, always described as something that benefits to an end user.
Therefore, no ground can be found to accuse Google for any wrong-doing for the sole purpose of making profit.
