Earlier quoted context omitted.
See, you could technically design something that does that. Per-port up to 100W charging it definitely possible. Basically you have a USB PD controller on every port with dynamic voltage control. This is all possible, it's just a HUGE pain in the ass (and costs a lot) to design that way. The problem is you essentially end up with potentially a giant, VERY expensive USB hub. And no one wants to spend $400 on a USB hub…
Which is why USB-C is bad, nobody asked for a protocol where the benefits are marginal but the downside (one of many) is that a proper hub that replicates the behavior of previous generations now costs more, and since nobody would pay that much, economies of scale don't apply and thus it doesn't exist at all or is available as very niche specialized units (kinda like opto-isolated USB hubs which go for $200. You coul…
The ask for the 'really expensive' $400 one has vastly more options and capabilities than the traditional USB hub. It's basically a Thunderbolt hub with even more complexity, so it's not unreasonable to think those would be damn expensive.
I'm honestly not sure why no one has made a standard USB2.0 Type-C hub. There's really nothing stopping you from doing it. I guess maybe because it could be confusing for a consumer? I agree, that's a huge issue with Type-C right now. It's very unclear by looking at the port (or the cable) what it's actually capable of. If you're lucky there will be a tiny symbol indicating some subset of functionality, but often times there isn't.
