As someone who also made this difficult decision to launch a product with only Chrome support: don’t feel bad, and don’t feel responsible for haters. Supporting other browsers, even those that are standards compliant, is a nefarious class of technical debt: from verifying scrollbar sizing to performance degradations, you add a tremendous amount of overhead to ongoing QA - especially important when you have a small team without dedicated QA resources or processes, and a clientele with an eye towards aesthetic detail. We owe it to our respective missions to focus on what matters.

For my part, I look forward to trying the product!
