Pro Free
Certs from LetsEncrypt are free, always, not just as a short-term trial.
Pro Automated

Cons
Con 90 days
Certs currently are only issued for 90 days at a time. The expectation is that users will automate renewal so that this is not an issue.
Con Domain-Verified only
Only class 1 certificates are available (the kind others charge $10 or more for). Lets Encrypt does not do Extended Validation or EV certs, nor does it offer insurance or the other features traditional vendors offer. How much of a con this is depends very much on how much you value those services.
Con Not for intermediates
His videos isn't for those technically inclined. More in-depth research is often lacking and may well be suited for newbies.
Con Terrible recommendations
He recommended Brave, DuckDuckGo, and ProtonMail.
