On the flip side, if I were a competitor to Basecamp, I love the access I have by advertising on Google on Basecamp. If Basecamp's business suffers from users going to an alternative, perhaps their product offering isn't as unique or valuable as they would like to think. Also I would point out that people searching Basecamp on Google rather than going to Basecamp.com may look for Basecamp type products. It's like if I search band-aid. Maybe I mean band-aid branded products, but giving me access to similar offerings is great for me as well as competitors
