Tech companies and their executives have, broadly, moved to align themselves with investors and adopted a posture of, often, disdain or outright hostility towards their users and employees. If tech companies don't value you, why provide value to them? If they back political positions hostile to your interests, why not return that hostility?
I listen mostly to progressive metal, which is kinda niche, and I’ve found pretty much anything I went looking for. Not sure about indie acts in general. Try browsing their download store - my only gripe with them is that the UI is pretty bad. The service is solid, though.
Also, seeing as they are DRM-free downloads, you could use Qobuz as a supplement to bandcamp for bands that are not on bandcamp, or vice versa :)
