I get why they need to kill off products. I took a few minutes to look through https://killedbygoogle.com/ and there are a lot of fleeting, gimmicky things on that list that should have never been released in the first place.
Google has an image problem with this. By releasing all these unfocused products into the wild, they've signaled that they will create unfocused products and kill off the ones that aren't hugely successful.
Now when they launch a new idea, people are no longer excited, but legitimately suspicious. When Google launched Allo and Duo at the same time (while Hangouts still existed), it sent a clear message that they really didn't care about product management and continuity or communicating to their users. They would rather be the ADD company that built 3 competing things and measure usage than to nurture and improve already successful products.
People don't like having the rug pulled out from under them and the repetition of this trope will continue to echo so long as it resonates with readers. Even if it's FUD, this is a big problem for Google.
I don't think Chrome OS will be on this list anytime soon, but if something shinier comes around, can you honestly tell me Google won't drop Chrome OS for the shinier thing?
How one can trust them is beyond me.
