From what I understand, producing a fusion reaction isn't the hardest part, it's maintaining it, extracting energy from it and preventing all the stuff containing the plasma from becoming radioactive. So I think by now generating a fusion reaction is not exactly breakthrough anymore? Sure the method is novel but I don't see how it helps with all the other stuff that's needed to make it useful.

Claims it's 1000x cheaper, so I suppose that's the breakthrough. Fusion has been achieved, you're right; next step is creating more energy than is consumed to do so; then commercialising it.

This makes it cheaper/easier to commercialise, but no closer (maybe further away, nothing claimed in the article) to the second step of getting more out than in.
