What are they supposed to do when their own government has a warrant? Ignore it and let the government shut down the whole site? This way they followed it without breaking anyones encryption, no back door, … this is a positive aspect in my view.
I use the RB4011, which even came with rack mounts. For the last year it's been working great (once you get the hang of how the configuration works). Can highly recommend.
I also use the CRS326, with a little less power than the RB4011, but with 24 Lan ports instead.
The only downside, compared to the UDMP, is the missing DPI
I recently sold my UDMP and bought some mikrotik gear, because the device hat very tight limits on what ubiquiti wants you to do with it. No wireguard was an annoyance I could live with, but disabling NAT was not possible and a switch backplane running at 1gbps were the final blow. Also I do not want to have to log into an online account to use my (maybe airgapped) router.
