Don't think your take is controversial at all. Rather, it's quite logical considering conmonly available information.
My POV as under.
Regulator must have surely taken the right step for customer protection. True.
Both Paytm and VSS are getting love from all corners because of the impact they may have made. True.
Other start-ups are crying foul, because next could be them. Maybe true.
Slight difference is that Paytm Payments bank and Paytm are two separate entities.
Bank's errors from years ago(due to which it has an embargo) has an inadvertent cascading effect on the Core Payments business of Paytm (listed mothership called One97 Communications)
Regulator took an action on a small regulated entity, leading to displacement of a large entity used by 100 million Indians monthly.
That's hard done, unfortunately.
Anyway, there are readily available solutions for Paytm to de-link from PPBL and partner with other large banks, and I'm certain that a solution will be arrived at before month end. Cheers!
