You have a sample size of exactly two films, and the first film was when basically everyone in the world was talking about that. you couldn't google the previous Star Wars movie at all, without coming across those TLJ/SJW articles going on about Rotten Tomatoes scores or whatever, and how anyone who didn't like the movie was some sort of closet Nazi.
It's not like TLJ came out then I suddenly *decided* to look for feminist star wars articles, because that wouldn't have occurred to me as a thing to even think about, before it happened. I noticed, basically because when TLJ came out the story was everywhere, complete media saturation. And I'm not someone who actually reads that many "geek" journals or anything. Just news.com.au for mainstream news and slashdot to skim over some tech news, that's basically it. So it's not like I delved deep looking for SJW - Star Wars related links, myself. Basically all the links I provided were a couple of basic google searches then picking from at most the first 2-3 links on the first page of results. e.g. if you google "alt right star wars" there are countless pages of articles across both mainstream newspapers and online journals all saying the exact same thing. Of course, if the fans of the movie are portraying haters as all alt-right neo-nazis then the assumption has to be made that haters are all against specific things in the movie e.g. it's too "progressive" or some bullshit like that, rather than focusing on what actual criticisms exist. Point is: the movie isn't really all that "progressive" anyway, but the media wanted to make it out that that was the sticking point, as a means of defaming the haters and sidelining legitimate criticism.
The point being, a lot of people out there were trying to drag politics into the discussion surrounding the movie. It seemed to be legit to bring that up as a discussion point, here, because that's an important part of how the fandom itself is going to be shaped in the future. The point of noting mainstream sources trying to do the same labeling with Solo is that they're doing it as an echo of the social commentary that surrounded TLJ, basically trying to glue their politics to the franchise (with some pretty tenuous logic), but they're also trying to shape the discussion into one about who's "worthy" to be a fan. e.g. note how they guy in the UK paper The Independent (a mainsteam publication, which makes it more relevant) tries to suggest that non-sjws are in fact Sith.
