It's really that simple for much of their products. I really don't understand why people still insist on using chrome, in particular. Google is a horrible company that would literally sell you into slavery if it was legal and they thought it'd boost their ad business somehow.
Part of the problem is that Google has an entire ecosystem that is ridiculously useful and is designed to hook people and keep them around. And once they're hooked it's really hard to move away from, even if it's in their best interest.
Unfortunately, parts of that ecosystem start deteriorating as they slowly abandon the product, until it reaches a point of being borderline useless. Then, they just deactivate it with little to no warning. Sometimes they just shut things down even if they're popular (such as Google Poly).
For example, their line of home security cameras are getting worse in quality and usefulness. I feel like it's only a matter of time until the Nest service shuts down.
I don't think Google will shut down nest anytime soon. They gather very useful telemetry about their "customers" and use that data to train models, and ah-hoc send your front door video to law enforcement whenever they want it.
Perhaps, but there is absolutely no development or bug fixing happening on their software. There hasn't been a software update in years, and the hardware has been a crapshoot for just as long.
