Lying is always bad propaganda, because it deceives and misleads the people
Even the women, who are already in the IT industry now, are leaving it in droves. Because many of them feel that they aren't being treated well.
Deceiving women, so that they will go into the IT industry, might work to some extent. But this will only damage women's lives, when they find out what it's like and decide to change careers. This is years of wasted life, where women might delay their marriage, having kids, and doing other things, just because they need to go back to school and learn another profession.
I think it's unethical to tell women to go into the IT industry and hide from them all the problems women are having there. This is almost like deliberately harming people.
