That could be due to GDPR. Some European registry companies believe GDPR makes the collection and publishing of WHOIS data illegal.

ICANN is currently suing a Tucows company in Germany [1] over their refusal to comply with WHOIS data collection, and ICANN published a Temporary Specification that allows/requires every other registry to hide WHOIS data globally pending the result of the GDPR court case [2].

Of course, that doesnt prevent savedotorg.org from posting their own "About Us" webpage explaining who they are.
