It would be, but that isn't what is being said here. It is being said that this specific, narrow, limited group of men is using the structures they created to keep articles that focus on their interests, Linux distributions, while excluding things that interest other people and not them, like bridal gowns. Because of the demographics of that population, the interests happen to fall along gendered lines.

Almost no one is interested in Linux distributions, but having articles on them doesn't somehow discourage any women from contributing and may encourage those who are into Linux. However, it does when topics that are socially coded as feminine, such as wedding dresses, are deleted because of their topic it does send a message about what is valued by the community.

Those social codings are also a problem, but a different problem than the one being discussed here. The best way to fix that underlying issue in this particular case would be for more men learn about the history of fashion and get interested in the construction of garments, rather than seeing clothes as trivial or beneath notice. In the absence of that change, the next best thing would be for these particular men to be aware of their bias and let other people talk about the importance of clothing even if they don't agree.
