no business in the capitalist world where selling ads is a billion dollar industry is going to make this available

How about an open-hardware open-source project on e.g CrowdSupply (something like www.crowdsupply.com/jie-zou/rggber but dedicated) where everything is setup to do so efficiently, e.g an HDMI/HDMI box where you put the signal in, get the signal out, and on its own does nothing but cool looking visual filters, e.g from color to black&white, yet when the user reconfigure it, with community made filter, it removes ads?
