Home routers are simple when they work and could be go terribly wrong when they don't. The issue is: a lot of ISP-provided routers are total trash that are buggy and reset themselves sometimes. So on the one hand, you get better support, but on the other hand, you may be getting a worse product. This may still be a better trade-off for most people. I wish ISP's would partner with eero or some other router company that actually make good quality fast routers.
