99% of the public doesn't donate either.

I'd be amazed of it wasn't at least five-9s, Facebook has 2B users.

You're underestimating how many web designers and devs are out there. These easily number in the millions.

Also, what grandparent said: "The public", in this case, is people who would donate, of which 100% know what a CA is.

Assuming Facebook's numbers represent two-thirds of all web users then I'm saying I'd be surprised if LetsEncrypt have more than 30,000 donors.

If we're quibbling about "the public" then the GP comments only make sense if "the public" means "people who aren't IT professionals", in which case I'd warrant that there are far fewer donors than 30k who aren't IT professionals, indeed it's got to be ~0.

Can't see donor details on the LE pages though? Mind you at approx.av.300k certs issued daily (https://letsencrypt.org/stats/) I concede I could easily be orders of magnitude out in my guesswork.
