Sounds like you work with a bunch of short-sighted, judgemental simpletons who cannot look past initial aesthetics for a product that has nothing to do with aesthetics.

Tbh I would run far the fuck away from that company if they can’t be bothered to sit down for a meeting where you explain that it’s an open-source project run by an extremely small team of nerds and that there is a commercial product available without the branding issues.

Everything you’re describing about your employer/coworkers gives me giant red-flag warnings regarding their decision making process.

Time to start looking for a new employer, or accept that they’re idiots and next time they ask about bots tell them “I’ve tried explaining this already but you dismissed me for silly reasons, so go pay for CloudFlare and stop bothering me”.
