Demonstrate, but don’t mistake demonstrating for political action. You may find it gratifying to stand on a corner in Berkeley with a sign asking drivers to “honk if you hate fascism” and elicit lots of honks, but that’s as politically effectual as taking a warm shower. Organize people who don’t normally vote to vote for Biden. Mobilize get-out-the-vote efforts in your community. Get young people involved.
While I'd agree there's a limit to the effectiveness of protest alone, it takes a certain kind of brain to think 
ing is the more politically effective move.
I don't even think they did. It just doesn't track:

trump loses
Its just a virtue signaling circlejerk. Its a networking opportunity to find other like minded people to circlejerk and network with.
"Oh I saw your piece on blahblah what 'nonprofit' do you work for?"
"What a bold display, would you like to do an exhibition in New York? My friends cousin has an avantgarde art gallery/fashion walkway and this would just be perfect for their next display about 'The fall of men'."
Trump losing was already a done deal, this was just a really easy slamdunk to showcase just how progressive one is to other progressives.
