The author focuses the entire blog post on remote third party services that are alternatives to popular third party services financed by data collection as a "business model". IMO, the single most important component of a home network is not any piece of the hardware/software outside the home that the third parties may control, it is the internet gateway in the home. Routers were the most important computers at the dawn of the internet, and IMO they still are the most important computers today. If the internet gateway in the home is ignored as a point of control,^1 then IMO all bets are off.
A significant amount of data collection by third parties can be eliminated or reduced by retaining control over the internet gateway. Arguably this amount is even greater than what can be affected by simply switching to using carefully selected alternative third parties. IMO, it is a mistake to believe that one can reliably eliminate/reduce data collection simply by choosing the "right" third parties. Whack-A-Mole, cat-and-mouse, whatever the term we use, this is a game the user cannot win. Third parties providing "services" over the internet are outside the user's control. For worse not better, they are subjected to market forces that drive them to collect as much user data as they can get away with.
Regardless of these privacy-destructive market forces, it is still possible to build decent routers from BSD project source code and inexpensive hardware. IMO, this is time well spent.
