I'm not sure if this is a positive or negative comment, but I'll explain why they do that.
There are two main ways to mask domain name whois information: 1) go through a proxy service, i.e., a company buys the domain under their name and gives you control, or 2) effectively use another entity's contact information with the exception of name, which is what Gandi does.
a) is rather risky to both parties. You do not own the domain, but another entity does. If you somehow lose the domain name or the entity holding the name goes under, you won't be able to get it back because it technically never belonged to you. The holder is also now legally responsible for the domain name.
b) is a much safer route with the constraint that your name must be attached to the domain name. This makes it so you always remain responsible for and the registrant of the domain name. It is yours.
