Jason raises a good point. While guys may colloquially have come to mean all genders, for many people it’s still a gendered term. In an age of equality and inclusivity, all businesses and especially those with broad influence like media organisations need to examine their use of language to ensure it’s not causing offence. While guys may be on the lesser end of the offensiveness spectrum (compared to IT terminology listed above like whitelist / blacklist), it doesn’t mean it’s not worth doing - especially given it costs nothing to do.
Just because it’s not an issue for you, doesn’t mean it’s not an issue to others.
I’ve also seen some women who don’t like being called “mate” because they think it’s a gender specific word used between males.
But I’ve also seen the argument that this is ridiculous and women also use it to describe their friends and always have used it. In fact, I know a lot if women who do use it. I don’t think we need stop using the term because some in the minority have this opinion.
If you are not part of a minority group then it’s hard to understand how it affects people. Australia unfortunately is very much behind the times in regards to this. As @Cassie84 said it costs nothing to make the change.
