I can't disagree more with the author of the post for the bad part. I manage quite a few things with letsencrypt, some having been set years ago. Each time I needed to take action I received an email from letsencrypt. I think they actually do this really well. If you setup things in ways that you get no feedback, you'll have bad surprises but that's the same with absolutely everything in life. The only difference with what was before letsencrypt is that certificates have a relatively short life, so a problem can appear sooner than it would before and it's automated. Like everything automated, it involve tools, infra and maintenance.
