This is the big one. Steam are currently seen as the exception to the rule largely due to Gabe's commitment to the gaming community. It's one of the few large American companies that actually seem to practice what they preach. This is probably largely due to steam being privately owned rather than publicly traded, so Gabe can afford to do stuff that benefits his customers, rather than milk them for the shareholders benefit.
Once good ol' Gabe is gone though, steam will likely eventually be sold publicly and the gradual enshittification brought about by the American shareholder will be inevitable, so whilst steams not an immediate threat like other American platforms, you're certainly not wrong to bring them up as a potential threat.
I don't take bro to exclusively mean male. But rather a male dominated group.
In the UK we use lads a lot; I'd say it's probably the British equivalent (tho bro does get used here too). IE: "I'm going to the pub with the lads." But that doesn't mean it's exclusively men, there's sometimes a woman or two in the group, it's just that it's a male dominated group. It's the same with women who have a female dominated group with a male member in (going to see my ladies/girlies etc...).
All of the above still assumes a male dominated use of AI though; and According to statista that does seem to be the case. Though as time goes on, the gap will likely close.
