Honestly I see this as anti-competitive of Google to award only YC companies this benefit. All, specific, or none.
(And for all we know, Google is willing to offer similar deals to other accelerators in return for some compensation.)

That’s a well-functioning market, I think.
It’s likely so that GCP can get its hooks in these startups early.
