I believe at one point UBNT did block outside management access, but then their customers voiced to bring it back. 

That said, I think they're taking security more seriously going forward.

I don't see how this is Cloudflare's fault really? Its the 
responsibility of network maintainers to... well, lets be blunt here, 
maintain their network. 

If part of maintaining their network involves updating bogon 
routes/filters, then that's part of maintaining the network that can't 
be lapsed. 

This is like the WISPs blaming Ubiquiti for their failure to update 
their CPEs and PtP devices for a security flaw that Ubnt released fix 
for more then a year before (and for not properly securing the 
management interfaces of their network devices). 

Or even better, the morons who blocked all of 172.0.0.0/8 even though a 
good portion of that block is live public IP space. I actually felt 
really bad for AOL having been assigned IP blocks from that space, since 
it had to have created customer complaints at times. 

There's only one person to blame here, and it's not the RIRs or Cloudflare.
