In 2016, Mohapatra wrote an open letter confronting the organisers of Mood Indigo — IIT-Bombay's inter-collegiate festival — for being 'sexist'. She pointed out that Mood-I, one of the most prestigious fests in India, has over successive years, failed to include female artists in its line-up of performers. She had written, "All the sponsorship, hype, marketing & branding of the world will not cover up the fact that you are a training ground for the worst kind of ‘boys clubs’ that create an imbalance in the world." She also stated that the women artists not only are paid less remuneration but are usually not able to headline the fest and have to perform under the 'umbrella' of a male performer. Sona shared that the institute had invited her to perform at the fest with a caveat that a male performer would accompany her. She also said that other so-called ‘premier’ fests like NH7 Weekender are following suit. Interestingly, every time Sona takes on patriarchy, she is trolled viciously online but as always, she takes the negativity in her stride and counters them with statements like, "You don’t scare me. I know my numbers & operate on facts, not feelings (sic)."
