"Matter of perspective" is not. First, I signed with Qobuz, as well as Tidal, because I wanted to stream the music I like. When I signed, all those recordings that are now missing were available, thus, this was one of the main reasons to join. Qobuz made the offer of giving me that music in order to have me sign to their service. Second, I joined because I want to stream music I like, not to buy and download. If I want to buy, I can do it in other sites and many times at a lower price. In addition, if you want to buy music from Qobuz you don't have to sign for their streaming service. Third, yes there are more persons mad at this state of affairs. You can check it in the Roon community web site. Some of those persons have contacted the labels directly. One contacted the CEO of BIS and this person told him that they were not doing this, nor had they asked Qobuz to do it.
It is interesting that some people accuse others of "blowing things out of proportion" when the conditions do not affect them, or when it suits them. As a paying customer I have the right to voice my concerns. And if the firm in question does not answer clearly, I have the right to bring those concerns to others that may be facing the same conditions.
As I mentioned in my original post, six weeks ago Qobuz promised to correct the matter. Different Qobuz personnel have given different versions. And if the rights argument is true, then Qobuz should have issued a notice to all its customers about this condition as soon as they knew it. Not to keep silent about it and wait until customers start complaining. Thus, yes this is a serious problem because it could mean that all those recordings will not be available anymore from Qobuz if they do not reach an agreement.
