Sadly, however, the article doesn't seem interested in answering that question and providing the necessary context. Instead it quotes authors of books, who seem ecstatic about the possibilities.
You'd be correct in calling me a cynic when I say that I've heard the "too cheap to meter"-slogan from back in the 50s when nuclear fission was the future.
But I try hard not to be that guy and genuinely want the same question answered - is this an actual breakthrough and a significant milestone in the big picture? Up to this point it's been hit-and-miss and many so called "breakthroughs" turned out to be small steps in the right direction, but not exactly quantum leaps.
Secondly, your attempt at being pithy about nuclear bombs is a complete loss. We previously only knew how to achieve an inertial confinement based fusion reaction with a positive Q factor by first setting off a fission bomb, and this was only done for the neutron generation to increase the amount of fissionable material exploded (which is why they are called fission-fusion-fission bombs).
We can now generate fusion energy in a way that is obviously confine-able. That's a major step, and it's not THAT hard to imagine many mechanisms of turning a hot droplet into energy. For example the hohlraum itself in an indirect system will obviously be heated by the reaction and could be used to generate steam. Engineering that makes no sense though if you can't get a high Q factor out of the ignition itself, hence the focus.
This four sentence post is a perfect example of OP's point. No insight, no though process, just a pithy negative reply.
Only an order of magnitude off, but yeah, physicists and spherical cows and all that.

A little sense of humour is lost on so many bitter souls these days, it's kind of sad. Lighten up, mate!

You do realise that the fusion reaction we're talking about lasted for less than a trillionth of a second in a miniscule area, while other practical designs are aiming for continuous operation in the half hour range to examine practical engineering challenges of particular reactor configurations?
A high Q-factor may be completely useless if the underlying concept doesn't work for actual power generation and one might be easier to achieve than the other (i.e. getting a continuously working reactor first and tweaking it to improve Qp). The question therefore becomes, what's the actual value of the result. The article doesn't even touch on that, while even some C-grade online publications provided context like that.
There's no industrial processes that make use of plasma in the 10s of megakelvins. It's also not moving the goal post at all, since generating electricity is the literal goal of nuclear fusion. If it's just heat you're after, we've solved that problem over 70 years ago. There's hundreds if not thousands of thermonuclear fusion devices readily available literally at the push of a button. But for some odd reason we try hard not to use them and focus on electricity instead...
