That hasn't stopped them before. Fitbit and Nest, for example. Granted, this is an order of magnitude more money to waste. Maybe they'll come up with a better strategy this time.
Google doesn't have a strong record keeping enterprise products around either. I would expect them to absorb this product, release a similar product based on the technology but fully integrated, then sunset Wiz asap.
it's obviously from their own quotes but you can get most of the names in their various customers use cases, joint PRs and the likes (and those required the customers' direct approval )
e.g. half of Fortune 100 use Wiz and I assure you most of them do not use GCP (or do not use only GCP)
