Not really - many people rely on Google Cloud and if Google made it harder for Spotify to compete (via, say, raising prices for Google Cloud for them), they'd have to be pretty specific to Spotify to not cause other customers to move to AWS or Azure.
Spotify has much bigger risks in their licensing deals.
cost it not a problem and google wouldn't do it. I'm talking about stealing recommendation algorithms and models. Have a peek new features before release etc.
