As somebody who has been around linux almost for as long as it exists, i must say that is a very strong statement.

In real life: systemd IS useful, Wayland is becoming (has become?) the default, ubuntu is the most popular desktop distro family.

He's not wrong though, the amount of Snap stuff you have to remove in a fresh install is starting to get a bit annoying (I usually remove at least the Snap versions of Firefox and Thunderbird and replace them with binaries from Mozilla - they will still self-update).
