Nupur Sharma's statements created an international controversy for India with several Gulf countries demanding a public apology from India.
Zubair was arrested within days of a complaint being raised on a tweet he made in 2018, while Nupur Sharma hasn't been arrested yet, even after causing an international incident.
IMO, Razorpay would have been forced to give up the data, Section 91 or not, since the current government doesn't really care about due process.
The link below gives more details about the tweet that led to Zubair's arrest.

Excerpts from the above article:
> According to the FIR, Zubair had used a screengrab of an old Hindi movie which showed an image of a hotel, with its board reading 'Hanuman hotel' instead of 'Honeymoon hotel'.
> In his tweet, Zubair had written: "BEFORE 2014: Honeymoon Hotel. After 2014: Hanuman Hotel".
> The complainant -- Twitter user @balajikijaiin, tagging the Delhi Police had written: "Linking our God Hanuman Ji with Honeymoon is a direct insult of Hindus because he is a brahmchari. Kindly take action against this."
> Noting the complaint, the police in the FIR said that the words and pictures used by Zubair in the tweet against a particular community were highly provocative and more than sufficient to incite feelings of hatred among people which can be detrimental for maintenance of public tranquility in the society.
