I actually had to go and reread the post because I didn't get a scare quote vibe from it and had to double check what part you were referencing. My interpretation of that was more critiquing/mocking views that treat science as a monolith, especially Established Science(TM). Of course, there are areas of science that are considered to be "settled matters" (or at least, more settled than most), but it's more productive to think of science as an ongoing process rather than an established body of knowledge. Like, I think the useful part is the way we consider what we consider to be established knowledge and learn from that. This is especially true in fields where new technology can place established knowledge in a new light.
I think that Twitter OP was more poking at people who use science in their appeal to authority arguments. Often what these people call science, I would call Scientism. Now that I reread it though, I can see the possible scare quote vibes
