I see why you are saying this but it is incorrect. MQA doesn't own Tidal and it was Tidal that took down your files. You misrepresented what you had uploaded to Tidal as being "music" when in reality it had test signals in it that could damage user equipment or at any rate, potentially make them go deaf listening to them. MQA likely notified Tidal of such and Tidal took down your content. Your beef therefore is with Tidal, not MQA.
In other words, you used deception to get your test clips into Tidal and once they figured this out, they took out your content. This is no different than Apple and Android store taking down apps that say they are one thing, but turns out they are something else.
You need to find another way to "get your own" data than than messing with Tidal as a service. They are not in the business of being your partner in this.
