OpenSSH might count, from the rant on their homepage:

Please take note of our Who uses it page, which list just some of the vendors who incorporate OpenSSH into their own products -- as a critically important security / access feature -- instead of writing their own SSH implementation or purchasing one from another vendor. This list specifically includes companies like Cisco, Juniper, Apple, Red Hat, and Novell; but probably includes almost all router, switch or unix-like operating system vendors. In the 10 years since the inception of the OpenSSH project, these companies have contributed not even a dime of thanks in support of the OpenSSH project (despite numerous requests).
