It's difficult for me to tell how many of the issues in that thread are serious, because there also seem to be a surprising number of people who come back to say "I solved it by enabling h264 in my browser".

On the other hand there are people who say "I ordered three, two work and one doesn't" which seems like pretty good evidence there can be real issues with the hardware.

I ordered three and they all worked and then one died. Fortunately they replaced it, though.

this doesn’t seem ideal for a piece of hardware that may go in a remote location.

It doesn't. But judging from forum posts, it seems like it was a common failure mode and it might've been fixed in later hardware revs.

Ordered 2, one was fine, other required a reflash to resolve a black screen. Worked fine across a variety of SBCs and desktops since.

Security is not top priority very obviously, but for a quick kvm on a system without bmc, it’s fine. Picks up DHCP quickly and responsive web UI.
