What is the real threat of Najwa Karam to withdraw from the theater in Stockholm?

Actress Najwa Karam gave a concert at the Stockholm Theater in Sweden, where she asked the audience to stop filming "Live" during her singing, and she repeated this request more than once, and the audience did not respond to her request, threatening to withdraw from the theater if they did not stop filming.
A video clip of Najwa Karam was circulated during her request to stop filming, and published on social media, where some described it as inappropriate behavior.

The artist responded to the circulating video with a tweet in which she said:

“We stay in the studio for months to reach the required level of recording, and it becomes good. I understand that some people want to shoot, especially in the era of social media, and we, as artists, must maintain our artistic standing, and this is the artist’s right.”
