It's not shutting down that I can see, I think its just the first sentence that can be misread to sound like that. I think this part of the message further clears it up imo.
Stepping up is exactly what's needed right now, and we're here to do it. These recent issues have forced us to take leave from our jobs to make time just to keep the wheels spinning. I hope you can understand that is why, for the first time ever, I'm asking you to donate directly to the people who make cock.li possible.
Your donation will make a real difference by telling us to use the money where it will help the most right now. We have a sizable war chest for legal expenses that has never once been used to pay us for our work. Problem is, if we can't make time to put that war chest to work, what good is it? We believe cannibalizing this fund to offset our lost time would put cock.li in a worse position, so by creating a new fund we can make it clear what we're doing while keeping our legal funds secure.

I've used the service myself for a good few years and have had no complaints so I will be and I would encourage anyone else to make donations to the site where possible. Monero being the best and most user friendly to use in this case.
Not to be overly dramatic but there are some alternatives like the above mentioned, but cock dot li is probably unique in its dedication to privacy, and now is the time to donate to them if you would ever.
edit: I've seen some speculation from people that there has been some compromise but nothing to that affect (so far)
