I think the reason Google puts up with this is that they know that it's very hard for new advertisers to build successful PPC campaigns.
And, ultimately, the end result of people using our software is that they will build larger campaigns that run longer and end up spending more money on Google.
Google can be counterintuitive with ad related stuff though, went to a great deal of trouble to support OAuth with adwords but as of yet are still missing report downloads which pretty much makes it useless for the vast majority of applications.
I guess when it's business against business, spending more money because of it is always a win for Google. They have shown more and more of late though they are prepared to put user experience before profit by banning low quality ads. I guess in terms of business against business it would take some major advertisers to oppose it before they went down the same kind of path.
Yes, I'm being snarky but all these talent acquisitions erode my trust that startups are in this for the long haul. Why give you my time or data if you won't be here in 9 months?
In the meantime, it's a very small time investment to keep an eye on your competitors' advertising strategies-- even if you're not currently running ads it's invaluable to know what your competitors are doing.

I realized that I was giving the same basic suggestions over and over again, and wanted to productize and mass produce strategies for building successful paid traffic campaigns- which usually involves doing market research and figuring out what's currently working in the marketplace.
