I suspect that there will always be some confusion about the "life-status" of Fluxus. That is because there are really two parts to it. During Maciunas' lifetime the two parts were completely intertwined. After his death, I think that part of Fluxus died with him...but a vital and important part continued on without him. That continuing part is not ... Read moresome sort of "new" fluxus, or "neo-Fluxus". It IS Fluxus. It may be Post-Maciunas Fluxus, but it is still Fluxus.
My article was actually prompted by a book jacket note about Dada. It said that "Dada died in Paris in 1924". The claim seemed absurd to me. Dada, like Fluxus, was/is and IDEA. Ideas do not die with the people that propose them. They live on until nobody is interested in them any more.
On the other hand, history is history. Marcel Duchamp and Tristan Tzara cannot be separated from Dada, and no discussion of Dada is coherent without them. George Maciunas was the engine that set Fluxus in motion. It is impossible to discuss Fluxus without celebrating/honoring/respecting his contribution.
