You need to care what other people think about your service or product if you are trying to sell anything (i.e. contribute.)
It's a short walk from not caring about what anyone thinks about "you" to not caring about what other people think at all. Don't fall into that trap.
Additionally, what ever happened to being an example and "being the change you want to see in the world"? What people think about you IS important, obsessing over a few people who don't like you (or your example, or service) is NOT.
