Let's Encrypt is for e-commerce / online shops

There are recommendations from bodies such as Payment Card Industry in their PCI-DSS standard (google search it) around what SSL certificates should be used however most small online shops do not go to the extent of getting audited or complying to PCI-DSS (costs).

FWIW, there is nothing in the PCI-DSS standard that precludes the use of Domain Validated certificates. Let's Encrypt certificates are perfectly fine for use in computer systems that are in-scope for PCI compliance as well.
