For now, I wouldn't worry. But if you get the sense that you are gaining more users than expected, and this starts earning you any actual money, then I'd consider preparing a rebrand. Or, of course, if you're getting into investment talks — any due diligence will/should bring this up and put a stop to it until resolved. Until then, I would possibly ignore it for now (unless it's an easy move).
