Yeah, I hear that frequently and I get it. The important thing, really, is that you have a cert and that you deploy HTTPS. If you can afford it and it's what you need to do to deploy HTTPS, then whether or not you get your cert from Let's Encrypt is not so important.

There are some good reasons behind the automation practices we encourage though, and if you're doing that stuff then the lifetime doesn't matter much. Worth considering regardless of who your CA is.

Thanks for your support!
