Fear not; they'll deprecate Chrome OS and Stadia in the next few years and add it to https://killedbygoogle.com/ , which I see has just added AngularJS recently. Google Cloud Print stuck out there too, since we had a big thing about rolling that out at work just a few years ago as the future solution for all our printing needs.
Google does kill off a lot of products, but I wouldn't hold my breath on Chrome OS. It is paying off for them in the education space. They have an OS that ships on cheap computers that work well enough for students. Gets them in the google ecosystem and the mind set of Chrome OS is what a computer should be. Not to mention contracts in place with school systems that probably nets them easy money.
