Indeed. We should just acknowledge that Jio started the revolution and thank them for it and just move on from there. Just use the best Non Jio provider available. If none are there, then use Jio till that point.
Jio knows there are other players in the market and has quiet(maybe they also see the blessings we shower upon them on this forum) . If they had monopoly over the broadband market , this would have been implemented already I guess. But there will be workaround for that also at some point as the WiFi router is obviously installed at your premises
The range the JioFiber router gives , I doubt if its even viable for them to pull off this public Wifi stunt
