It's not reflexive-contrarianism as such; it's that the science press has historically been so, so bad that cynicism is the only healthy response. Think of the last 5 things you've seen in the science press: which ones were overemphasized? Which ones were exaggerated to the point that they didn't reflect anything meaningful about the actual result? And thinking back on the press releases over the years, what percentage of what you've read end up having an actual effect on the world? Add to that the fact that this is about fusion breakthroughs, something that has been wrought with complete disinformation by the science press since the late 1940s. Of course people here are going to be cynical about it.
