Jio Gigafiber could have picked up traction in its inital startup but the greedy FUP packages just put off a very large number of the population. IIRC, only recently did they introduce unlimited plans (Not actually truly unlimited) since people just didn't care about them. Security concerns are also a great factor since Jio seems to love collecting data.
Your local ISPs rates will always be a better choice over Jio Gigafiber unless you have absolutely no options and the ISP is charging out of their ass.
They have always been pathetic, only thing I'll agree is that they helped bring better internet prices/packages for the general public. While monopoly ain't great, those greedy telecom bastards deserved to go bankrupt with the Pre-Jio packs and pricings including those VAS that deducted balance out of nowhere.
