Sure, Google is "special" among large vendors covering a wide market (Amazon, Microsoft) that "fails fast".
But if you stick to long running products, even with Google, you are unlikely to have that issue. Eg. so many companies are relying on Gmail and Google Docs for their work: I don't think anyone feels they are going away anytime soon. Basic Google Cloud services (eg GKE) are likely to keep humming along fine.
But there are a number of smaller SaaSes that will show up with a specific niche product (like Firebase Dynamic Links here) that may be gone as quickly as their VC capital runs out.
