Maybe not grandma, but Bob the accountant could install pihole or tor. If only a small fraction of non technical people start using privacy focused software, it would be a big win for the open internet.
While I agree in principle, unless people are becoming unchained from their ISP-provided router/modems, I just don't see this gaining much traction. I really hope this succeeds (or something like it), I just feel that the current ISP environment is not conducive to such disruption, especially when 98% of users are running vendor-provided modems with the default configuration.
Does grandma even _want_ to install packages on their router (which is likely a modem combo provided by the cable company), let alone know what a router is? Grandma wouldn't even be able to get her shows if she messed with the MoCa for FiOS, for example.
