@micahflee @upshotknothole @jerry @tessaracht A big question on my mind is, why do you think it is bad for Let's Encrypt to be the world's biggest CA?
Let's Encrypt is a non-profit, created in the public interest. I can't think of a better type of organisation to be trusted with this responsibility.
If it makes you feel better, one can imagine the likes of Symantec (probably the biggest CA today) eventually offering a free tier.
