1. Google does not have a solid track record of killing things. IF you actually go through the list of all the "products" Google has "killed", you find that 95% of them are just consolidated into other areas of the Google product stack. Stadia was a herculean undertaking that involved a capital deployment that, at the time, was unprecedented in the gaming space. Stadia wasn't killed because it didn't grow quickly, it was killed because it didn't grow at all and was losing money, not to mention failing to acquire market share. Would you prefer the product be destroyed to put it on indefinite life support like Amazon has done with Twitch?
2. Google is an absolute giant in corporate communications via G-Suite. Just because their video chat didn't win out doesn't mean they have no competency in the space.
3. Google now does have a strategy for comms tools. Workplace text chat is part of the Gmail end of G-Suite, all video chat is under Meet. This would slip right into their new Meet ecosystem. Unfortunately many of the people who parrot your talking points also were the ones criticizing google for attempting to reign in their comms ecosystem because it was "killing" products, when in reality they were just being re-bundled
4. Google delivers legendary levels of hardware support for their Pixel devices, the absolute best in the Android ecosystem. Not to mention they run the single most compatible smart home ecosystem and have supported Chromecast for a decade.
Can you even name a division that Google could just spinoff in your world? Stadia couldn't sustain itself without the Google Cloud backing it. Really tired of all the HNers essentially making up this narrative about Google when it rally doesn't exist.
