Subscription models are only as sustainable as long as there's interest. To keep that interest, there has to be new things added to it. For something as long-term as Game Pass (which is going to be forever considering Microsoft seem to be basing their entire ecosystem around it), they need new stuff at all times, which they are achieving so far. Buying new studios ensure they have plenty more games to go onto their own service, which is what they need to make it a more attractive proposition. With xCloud being folded into Game Pass from September, you don't even need an Xbox console to play (though that opens a whole different discussion about personal experiences with latency and such). Once xCloud hits PCs, that reach will onlygrow further, as even those who don't own a gaming PC can jump in on what's being offered. I feel Microsoft have been building up brand recognition on the Switch purely for this reason.
As for the numbers - we will never know. All we can do is trust what those in the business tell us. And if a publisher of indie games is saying that Game Pass improved their brand recognition and sales, I'd trust in them to know their own numbers.
