Why has UP Film City become a bone of contention between parties? | Debate

The mouth piece of Shiv Sena, Samana, has been known for attacking the leaders and acts of other parties. This time it attacked the Film City project of Uttar Pradesh. It was written, "If someone says that he would take away Mumbai's business then nobody has the sufficient guts to make it possible. Taking Film City from Mumbai to UP is not like taking away a chocolate from a kid's hands"
On the other hand, SP has jumped in as well. Akhilesh Yadav tweeted, "Respected sir, take care of the state first"
Now Sidharth Nath Singh has given a reply and said that Thackeray could not sleep these days
