- Take the amount you paid for certificates last year
- Divide by any number, let's say 10
- Donate that amount to LetsEncrypt, and continue to get free certificates all year!
I agree with some commenters that it would be great to see LetsEncrypt bolster their revenue with reasonably-priced offerings such as wildcards and EVs. But you can't argue with the progress they've made so far. If there is enough community demand, I'm sure they'll get there.Though their stats page[0] appears to be broken, last I heard they had surpassed 5 million certificates. To meet their current funding goal of $200k for a month, that equates to $0.04 per certificate per month, or $0.48 per certificate per year!
EDIT: Their stats page is back. Looks like they have reached 10 million certificates. So halve the above numbers!
