LWN isn't anti-GPL. I don't know what made you think this -- the title is obviously a reference to people thinking the GPL is "scary" and that the SSPL takes the GPL and actually makes it scary.
The GPL has more than run its course and it’s time to move on. Many people recognise that, and that’s what we’re seeing.
This is just typical "people are saying" weasel words. The GPL and similar licenses still definitely have a role to play in the current state of software.
