People are reacting negatively to your comment, the reason is that however accurate your complaint may be about most such reporting (IMO you are correct), you have chosen to attach it to this article. I find no evidence in this article of “tone implying life is about to turn up”.

I think you have misread the tone. The article certainly has a tone of excitement throughout. But it’s excitement for further knowledge, in general.

Of the possibility of life showing up elsewhere, it says only this: “Scientists are still a long way from answering whether life could originate on Enceladus”
