Galvanised I was sarcastic, it's true, and I'm sorry for not offering a more measured response.
I'm just really, really tired of women spending time they can't spare, energy they can't spare, and money that they can't really spare to create events and organisations and campaigns, and other women then complaining because the event/organisation/campaign doesn't provide everything that they want. I think if you are going to complain that a volunteer-created event doesn't offer what you want it to offer, then the solution is for you to join in, and help create the things you want and need out of that event.
I'm a single parent. When my DS was small, as well as looking after DS I was working part-time and overseeing the care of my disabled mother (ie I was looking after her, and she certainly wasn't in any state where she could offer childcare to me!). I know how limiting it can be when you want to do xyz and you can't because you can't find childcare, and when you can, you can't afford it. (And I had significant health problems myself, so was always tired.) But the answer to my frustration, and yours, isn't to complain that already overworked volunteers aren't doing enough - it's to pitch in yourself, when you can.
If you want something done or something provided, and you can't offer time to volunteer yourself, maybe you can send a fiver to help with the fundraising. If you can't send a fiver, maybe you can offer to retweet/FB/whatever fundraising messages. And if you can't do any of those things, then you can at least have a measure of understanding why the volunteer event organisers can't do everything you'd like them to, either.
