> It's frustrating to see the occasional conspiracy theory suggesting that the Let's Encrypt project somehow wants to backdoor the client in order to compromise people's servers
That's not the only reason someone might not want to use the LE client. Here are a few others:
1. The LE client might have a bug that causes problems on my server.
2. I may have done something non-standard to my config files that the LE client undoes.
3. Someone may have compromised the LE client or one of its dependencies without your knowledge.
I agree with those concerns, and I definitely don't mean to suggest that people who chose not to use the client all believe in conspiracy theories about the developers' intentions.
