All of its interpretations of QBist "Core Position" on the wikipedia page.
Most importantly, nothing I can see in the QBist pages has anything to do with actual experimental work. It's a framework for viewing what the mathematics of human theories of QM "mean" and how to interpret that. However, nothing of what they propose is required to explain what we observe, experimentally.
More generally, no "interpretation" of QM is required to apply the theory in generalizable, predictive ways, so all this work isn't really helping us move science or engineering forward.

You're making very broad claims here. Whether you find QBism plausible or not, it's certainly not "scientific garbage" and also fully compatible with experimental data (as is any other interpretation of QM).

So you would say that orthodox views of quantum mechanics (Copenhagen, shut up & calculate, many worlds (as it's becoming increasingly popular)) explain what we observe?

I disagree, once again. Have you actually deeply looked into the issues with QM? Many of them are linked to questions that come up in quantum gravity, so I would argue that getting QM right would be a very good first step in making scientific progress.
