This is a fair question, why would anyone spend money on a free service. Is there something that the free service does not provide..?

Could I go wrong if already more than 20m websites have been secured by Lets Encrypt?

Image & Credibility
Image & Credibility Online is one of the reason that businesses do not use Lets Encrypt.
Let’s Encrypt is equally secure for your website just like commercial SSL certificate.
We recommend Lets Encrypt for internal use, simple projects or personal blogs.
While shopping online users make decisions over very simple things such as speed of the website, image resolution, SSL Certificate provider may play part as well.
The moment an online user finds out that you did not consider investing in an SSL Certificate, they will review the credibility they had placed on your brand or business.
Investing in an SSL certificate confirms awareness and commitment to fight cyber-attacks and most important protecting the information of your clients.
But of course Lets Encrypt is better than no SSL at all.
