Like others said, convenience. And sometimes that makes sense. But consumers should think critically and research before buying/participating in an all in one type product or ecosystem.

A personal example for me is my network setup. My modem, router, hub, and wifi AP are all separate devices. I switched to that kind of setup when Comcast started started making consumer routers public wifi hotspots by default. Yes, you can turn it off but it shouldn’t even exist in the first place. My setup is more difficult to manage, and has more points of failure but it also limits the level of fuckery any given vendor can do to MY network.

Edit: s/internet/network. And spelling.
