Why is William Dalrymple Not Liked On Indian Socials

I have lately developed an interest to learn more about Mughal rule, so went into a popular bookshop in Delhi and asked for any recommendations on the topic. The assistant pointed towards an entire section, mostly stocked with books by William Darlymple.

Another customer interjected and advised me not to get any by him. When asked why, he couldn't give me a satisfactory answer.

Then whwn reading up online, whenever his name came up, esp in the more recent news story of the demolition of a 17th century monument in Agra, the comments were raw.

I went ahead and bought 2 books anyways. He comes off as pretty objective and balanced and seems to have done thorough research

So then why the hate?
