I am also copying another response:

My point is that there is nothing else for issue related to other discriminations. And yet, before thinking whether those men (who showed up) maybe are also oppressed and discriminated, they have been simply labeled as "men" and therefore intruders, by definition. I would think that an oppressed community would realize the commonalities with other oppressed categories and use this to expand the struggle to them as well. Instead the rethoric behind this article makes me think that this is one of those events which is ultimately functional to the conservation of the status quo: big tech companies which sponsor the event and gain some visibility and good karma points to boost diversity while nothing really changes or is done to address the fundamental issue with discrimination (in general, not a specific one), because this is ultimately functional to the companies, which can leverage them to fight a fragmented worker's front.

The difference between women in tech and the examples you made in my opinion is exactly that the examples address the whole universe of people affected by a particular discrimination or disadvantage. In the case of woman in tech, a single aspect of a more general problem is cherry picked. Again, I don't want to use moral terms, I just think in terms of objectives to pursue. I have the feeling that the objective for some of the people who are talking about "intruders" is not to improve the culture in tech to eliminate discrimination and privileges, but a simple issue of "we want to be a bigger % of the privileged". As such, I feel that the struggle is inherently reactionary, entrenching the overall dynamic of discrimination and fragmentation of the working class, simply tweaking a bit the appearance.

While it's for sure true that organizing all of this did not happen in a vacuum, I would also argue that ultimately this is also the result of a "more privileged" status quo, bigger amount of power and influence, compared to other minorities that simply can't achieve the same. Rather than using this power for the benefit of other oppressed, it seems that the idea is to just fight your own battle. I don't want to say it's wrong, I just think that this does not fit in my idea of struggle to improve the society. If I were a man who needed a job and I was labeled as intruder, non invited or something, I would have a problem tomorrow to join a union with those who labeled me, because the feeling I would get is that there is no mutual recognition of common problems and class. In turn, this means that when tomorrow there will be the need to protest against the various Apple, Microsoft, etc. Workers are going to have less power, not to mention that some of the people will think that since X% more women are hired in tech there is maybe nothing to protest in the first place.
