Ha ha! My inability to use it at appropriate locations to get 2% cashback? Talk about being full of oneself.
And full of contradictions too. First you rant about my inability to use the card at "appropriate locations" and then you claim those who have been able to get the card have been able to enjoy it. I have the card and one more in my family. So no sour grapes of any kind. I know what shopping means and how it differs from dining or travel and I don't see the benefits. I'm not going to go around finding MCC of merchants -- may be you have the bandwidth for such niche research but most normal people don't. We try scanning at a shop in a mall and when we notice we consistently don't get rewards as promised we trash the card. I may look at MCC when I'm swiping for a lakh which counts towards a milestone but am not going to look for MCC with 100-200 bucks kinds of payments.
As for many of "such kind" that you claim "enjoy it", check out the Jupiter Community and even there, everyone is upset with the revaluation. And now of course, Federal Bank is pulling the rug under the main Jupiter account too with its ridiculous new charges. Jupiter's initial cashback on the Edge CSB was just marketing hype to drum up interest and that is why they are getting the stick from users, not because of sour grapes, etc.
If you have a problem with Tata Neu trash it for all I care. For me, I think its far superior to Jupiter Edge CSB based on my real experience. And I would wager so would most on this forum that is knowledgeable on credit cards.
As for chemist shops, good for you. Going by your claims on the Jupiter Edge CSB, I would like to take it with a large pinch of salt, but enjoy 20% if you indeed are getting it. As for me, I lived in Powai and interacted with 7-8 chemists till I got 15%, including the likes of Welless Forever and small but reliable pharmacies. As someone who was fairly involved in the community and I've interacted with others too in the area looking for discounts on medicines and the best we were all able to find was 15%. May be we are fools compared to your eminent greatness, but I'd rather be a fool than pompous.
