Front companies are a well established method of operation certainly in spycraft (see the latest Crypto AG revelations), but also in internet hosting.
For example, Google requires their employees at certain data centers to only wear the badges of / pretend to be COPT employees [1].
Additionally, the Wikileaks AWS Atlas [2] showed show how yet another major company does this. I realize these are cloud data centers, but the similarity between them and hosting registrars, in terms of "internet power", is very complementary.
