It won't. They have an ability to create a sister social network which uses Tidal brand and seamessly integrates in Tidal UX aimed at artists based on Nostr which will heavily use kind0s. They've recently launched Tidal Circles closed beta which is a Twitter-like experience for artists. It doesn't make any sense unless it uses Nostr under the hood. As it allows anonymous posting I suspect it is in fact a Nostr client.
