In his statement of resignation he says that given recent events the Tor Project no longer meets his ethical standards, and that he will be ceasing all support, including financial and technical.

"Dear friends,

Given recent events, it is no longer appropriate for me to materially contribute to the Tor Project either financially, as I have so generously throughout the years, nor by providing computing resources. This decision does not come lightly; I probably ran one of the first five nodes in the system and my involvement with Tor predates it being called "Tor" by many years.

Nonetheless, I feel that I have no reasonable choice left within the bounds of ethics, but to announce the discontinuation of all Tor-related services hosted on every system under my control.

Most notably, this includes the Tor node "Tonga", the "Bridge Authority", which I recognize is rather pivotal to the network

Tonga will be permanently shut down and all associated crytographic keys destroyed on 2016-08-31. This should give the Tor developers ample time to stand up a substitute. I will terminate the chron job we set up so many years ago at that time that copies over the descriptors.

In addition to Tonga, I will shut down a number of fast Tor relays, but the directory authorities should detect that shutdown quickly and no separate notice is needed here.

I wish the Tor Project nothing but the best moving forward through those difficult times,

--Lucky"
