I read through it for the details.

It was net negative, requiring 2MW of power to maintain hydrogen plasma in a state analogous to fusion. The major achievement of this particular experiment was doing so without energies equivalent to a fusion reaction damaging the containing assembly.

It was purely a test/demonstration of the containment of fusion-like conditions.

Ads on a service I directly paid for was the line for me as well. I have no tolerance for that nonsense and it boggles my mind that anyone else does either.

If even a tenth of the subscriber base for any of these services cancelled because of ads they’d be gone so fast you’d get whiplash, and yet most people just put up with it.
