There is a corporate friendly way to handle this discussion. Here, I’ll even write it for you:

“Hi [Team],

Thanks for reaching out again about this issue.

I have made two previous attempts to provide guidance on this matter, but my recommendation was dismissed without appropriate consideration due to first-impression aesthetics of a product that is provided for free by a small team of dedicated nerds.

I attempted to explain that a corporate-friendly paid version exists but never got that far in our conversation due to your team’s outright dismissal of the product I know to be both effective and appropriate for your use case.

Due to these circumstances, and your team’s apparent priorities, I recommend you pursue an expensive contract with CloudFlare.

If you change your mind and would like to revisit this matter, I’m happy to set up a meeting to present the details.

Best of luck,
