What justification makes VOA to shut down its Bangla radio broadcast service?

Sadly the largest U.S. international broadcaster, Voice of America (VOA) which provides news and information in 45 languages to an estimated audience of more than 280 million people weekly through its satellite, cable, FM and MW on a network of more than 2,500 affiliate stations since 1942, has shut down its most enriched Bangla radio broadcast service in a press release distributed on July 13, 2021.
