Link speed has always been measured in bits/s or as sibling comment suggests baud which is, still, just bits per second.

Obviously a huge part of this is marketing for modems, ISPs, network cards, etc. but it’s consistent. The conversion to GB/s is fairly simple and doable with the super key, or super space on Mac in every modern OS…

I agree with you that the difference is irritating, but wouldn’t have done any different if I were Cloudflare.
