Given the rampant discrimination against men that exists in the modern tech sector and that even stating "maybe women naturally prefer to do other jobs than tech" gets you fired, what exactly do you have in mind that would make it even more welcoming?
Please don't post in the flamewar style to HN. Your comment here broke several of the site guidelines. Would you please review them and stick to the rules when posting here?
What it means to be "welcoming" is rather subjective. But there has been widespread adoption of discriminatory policies designed to make women get offers more frequently than men as I have shared in a previous comment [1]. I think this is what was being referred to when the above commenter talked about companies being more welcoming to women.
The extent to which discrimination makes tech more welcoming is debatable. It does have the immediate effect of increasing the number of women in tech roles, but it does so at the expense of putting them in an environment where they know that their male co-workers were held to a different standard and vice versa.
Edit: your comment history shows a lot of political and ideological flamewar comments, and we've already had to warn you about not taking HN threads into gender war. If you keep this up we're going to have to ban you, so please don't.
