So you trust yourself more than everyone behind Let's Encrypt, et al? Of course, you don't have to use Let's Encrypt so you do have a choice.

I think the criticism was meant as one of the CA model, not Let's encrypt specifically - you have no choice about using CAs if you want to use https to serve a site to normal users. Also, I'm not the OP and think Let's Encrypt specifically is a great idea, already on the waiting list.
