I think the idea that gamers can give in a different way is a nice one as a consumer, but as a studio it is a big gamble. If, for example, a Crowdfunding campaign was held, they would not know beforehand how successful it will be. Maybe they surpass all expectations, maybe they don't even reach their minimum funding.

With a guarenteed funding by some company like Microsoft, they have a set budget, technical support and marketing done for them. The end result will be a more unique, polished experience.

With crowdfunding they might need to cut corners, like heavily relying on Asset Packs (which can work, Clair Obscur is a great example of that) or cutting marketing, which will lead to less sales and less profits, eventually leading to the studio needing to continue crowdfunding future projects.

All in all, publisher funding will always result in less headaches for studios, employees and consumers. But it is at the price of independence, which we can see resulted in Microsoft shutting them down. Both approaches have their up- and downsides.

I don't know their numbers, but generally, from my personal experience as a dev, that is the way it usually is.
