I’m with you OP. I’m surprised by the lack of rationality in this thread.

Yes, a more professional looking solution would benefit all parties, especially if the developer wants supporters.

First impressions matter. If anything about the first impression is polarizing, potential users and supporters of the project will be lost. Your coworkers’ reactions have proven that the solution could be marketed better. It’s not your job to hard sell your coworkers on furries and .lol domains.
