Exactly! As Apple dismantles its ecosystem, the more it fragments its user base. By ending product lines, they're forcing people to look outside the Apple ecosystem for more and more devices. The more Apple customers look outside the Apple ecosystem, the more likely they are to leave it. While other vendors might not deliver the same overall experience, and especially Mac OS, they provide a lot more options. For example, some folks want Ethernet built into their laptops, some want upgradable RAM and storage, some want more power, and others want Nvidia GPUs, and so on. Even though things like Apple TVs and Time Capsules might not be particularly profitable, they keep people in the ecosystem, or at least make it easier to be in it. Consequently, if Apple has a great ecosystem, people will stay in it; if they don't have a great ecosystem, people might leave. If people stay in the ecosystem, they'll keep buying the more profitable products: iOS devices.
