Generally, and probably inescapably, science fiction ends up being entangled in the author's worldview. (Either positively, as you note, or negatively, as in the warnings of dystopias, or in an arbitrarily mixed way that still has to be grounded in the author's point of view about society.)
The two major periods in time in publishing when that was less visibly true is at the start of the last century when Hugo Gernsback (for whom the Hugo Award is named) was soliciting stories that were basically "what neat new use case could wireless technology address?", which can be viewed as a way of creating a literary prototype of what the reader might see in a few years. Of course, even if these stories might be seen as focused on predicting the near future, Gernsback is also literally organizing his readers into the Wireless Association of America, which directly advocates for political and regulatory decisions.
And in the 1940s-1950s, the science fiction mainstream felt the distinguishing feature of their genre was a focus on a scientific conceit, as opposed to melodramatic adventures. This often meant that they ignored how their stories reflected their worldviews. For example in unconsciously repeating their expectations about the gender roles of housewives. But ignoring one's opinions about culture or society doesn't mean they don't exist in what you are writing.
