They already refused to back down, even after requests from Let's Encrypt lawyers. Backpedalling now in response to the PR crisis would not be enough, in my opinion. I'd only consider them again if they were to make a decent donation to Let's Encrypt.

I had a Comodo cert expiring in a year or so, but still went with Let's Encrypt since I was setting it up for other domains.

Well, colour me impressed. Looks like they have indeed done the right thing. Fair's fair, I'm going to go ahead and renew my Comodo cert.

I had one just about to expire, and this was my motivation to switch over to Let's Encrypt.
