question is: would yamli be able to enter adwords on google's service name? I believe yes. In that case, what google did is fair game. The other issue is the fact that it's much cheaper (or free) for google to enter ads into adwords, but I don't think anyone would propose google refrain from using adwords altogether. Or would they?
Really? I'm not so sure. I think it would be a big mistake and would open themselves up to competition. However, it doesn't -seem- evil to omit search results.
I don't know. These are shark-infested waters, so I won't venture further.
