No. Companies advertised with us have paid our ad network for a spot, and does not mean that Tab for a Cause endorses them. We don't choose specific ads ourselves (as awesome as that would be).
The funnel goes: Company --> Ad Network --> Your Tabs. We have filters in place to ensure ads are family-friendly, however, ads sometimes get miscategorized and leak through our filters. This may mean seeing an ad you disagree with, but the money still goes to the charity of your choice!
