any media that requires a permission from an external party to play can and will eventually be taken from you. at least qobuz seems to be drm-free (i don’t use the service, so don’t quote me on that) so you should be able to make a copy of what you listen to. at least before they enshittify.
still, i’d personally not feel comfortable entrusting a streaming service with being the gatekeeper of the media i want long-term access to.
i mean… blocking lists are universal, but the other features ublock offers are not - i’m making heavy use of ublock’s dynamic filtering panel and per-site switches. one important thing i use ublock for is to whitelist which sites get javascript permissions and to get rid of remote fonts to make pages more readable. those features need manifest v2.
if firefox drops manifest v2 and you’re relying purely on those inbuilt blocking lists then you might as well use the manifest v3 version of ublock without seeing a difference, right?
the devs like to pretend that it is and say how only a small part of it is proprietary, but it’s a deceptive PR stunt because they’re counting the whole chromium source into that statistic. if we don’t consider the chromium source they didn’t write, their own vivaldi code is largely proprietary.
regardless, a program consisting of 99.9% free code and 0.1% proprietary code is proprietary as a whole - you can’t audit, modify or redistribute copies of it as long as any non-free code is present.
