<div style="font-family:Arial;">SSL/TLS does not just give privacy, it also certifies that the published site has not been tampered with (man-in-the-middle). I would suggest that as the purpose of the whois database is to serve accurate data, including information which may be of use to professionals dealing with cybersecurity events, that the request is totally reasonable, and not "just because". <br></div>

<div style="font-family:Arial;"> The overhead for HTTPS is real on older hardware, however the most recent generations of CPU have some new fangled magic bit which whilst I do not claim to know how it works, but does have the effect that the HTTPS overhead is very much reduced in real life implementations.<br></div>
