Ubuntu 18.04 is EOL, unless you pay for extended support. How many people are paying for that support?
I hope the people complaining about the VSCode incompatibility aren't people running EOL software and complaining that other people aren't keeping their software compatible with it.
I upgraded a number of servers to Ubuntu 20.04 because Ubuntu 18.04 was EOL. I also upgraded my desktop to Debian 12. ;-)
