I had to look up the meaning of schadenfreude.
pleasure derived by someone from another person's misfortune.
But this is not misfortune. This is the well deserved consequence of the intentional bad actions of the Blurt owners (account freezings, disabling the ability of various accounts to receive downvotes, etc).
Schadenfreude is a German word that gets some usage in American English as well. I noticed some anchors, within them noticeably Ben Shapiro using it fluidly in full english context.
