What I Think

Yes it is permissible. When a person or company Advertises part of the budget is counting on no gain on the ppc. If you do it knowing who is benefiting then I think it is wrong.

The question was once asked. There is a tendency of people who buy from Walmart before they go to country knowing they will return it at the end of the summer. For the fact that Walmart has a very good return policy. Is it wrong because if a yid has stock in Walmart he loses out on the returned merchandise.

The answer was it is fine. When a stockholder buys stocks. The person knows of there relaxed return policy.

Same applies over here.
