Because it&#x27;s supposed to be independent of the Let&#x27;s Encrypt brand, with Let&#x27;s Encrypt hopefully being one of multiple providers of CAs speaking the ACME protocol and this client being one of many clients compatible with them.<p>There has been a lot of misunderstanding and FUD about how you can use Let&#x27;s Encrypt because of the relatively heavy and by default &quot;invasive&quot; official client. This hopefully helps to make it clearer that it is one option of many.
