At least on British and Swedish news, it received significant coverage. Related articles are still pretty prominent today, a day later. I think people who somewhat follow the news will have seen it. It's also definitely not going to lead to any practical application in the foreseeable future, which is why the coverage isn't some week-long story. My own understanding of fusion is very limited but the breakthrough is about getting the actual fusion reaction to produce net positive energy. A big deal in physics but the amount of energy produced was tiny, it was far less than needed to power the equipment, the fuel capsules require extremely high-precision manufacturing that does not scale, we still don't know how to build an ignition chamber that could last with an active fusion reaction, and we don't know how to usefully capture energy from the reaction either. To use a flight analogy, yesterday was the Wright Flyer covering a couple hundred meters before an unintended landing. From there, it's a long way to cross-continental passenger flights.
