Not a command-line tool but the network link conditioner is also really great. Never seen such a tool on another OS

You can simulate a really bad network. Latency, bandwidth, packet loss etc. Great for testing but also if people insist on cameras being on. Just screw up the connection so bad that everyone gets annoyed with your blocky image and robot voice and suggest you turn off video and then you make it 'magically' ok - lol

You can do that with standard Linux tooling available on every distribution, see https://man7.org/linux/man-pages/man8/tc.8.html. What you're specifically looking for is `qdisc netem`, it can inject packet loss, reordered packets, duplicate packets, delay and more.
