Yes it's annoying but still don't get what the fuss is. You said it's because they don't care about the bigger picture. But the bigger picture is they are doing everything to cut cost and adding extra chips is not worth it. They aren't exactly hailed for their built quality.

The whole point of the post is that they didn't even have to add an extra chip -- just a single resistor. It's not even a cost-cutting behavior, it's just a simple mistake.

I’m not sure it’s a mistake so much as a lack of caring.

pedantic: they have to add 2 resistors, one on each CC line. The Raspberry Pi famously screwed this up and shared a resistor for both lines. https://www.theverge.com/2019/7/10/20688655/raspberry-pi-4-u...

While I'm glad that they took the time to hold support's feet to the fire over this, doing that sort of thing is almost certainly a waste of time. Seldom will you find a support team who can understand a technical hardware problem like this, and even more seldom will you find a company that responds to this with anything other than "nothing we can do, sorry". You're not going to get the "Wow, that is our bad, we'll r…

Great comment… It makes me appreciate that last year I bought a part for my car that didn’t work great but was ok. They said exactly that- they would gear up to manufacture a better one and get back to me. About 8 months later I got two redesigned parts free in the mail and got to keep the initial one.

Earlier quoted context omitted.

The required resistors are literally a tenth of a penny each ($0.0011/ea) on DigiKey[0], probably cheaper elsewhere. You need two of them. Two tenths of a single penny. Exway is charging between $350 and $1650 for their skateboards, from what I can see on their website. I highly doubt this was done for cost reasons, even including the additional assembly costs, which for surface mount resistors would be very low. Thi…

materials costs are not the only consideration. they have to arrange for a secure supply, retooling, QC checking etc. to do it properly. I imagine they got the cheapest engineer to make a functioning product. Changing their whole production line for a $0.001 component is hardly worth their time in this product segment, however debatable the ethics or PR of it is.

Wouldn’t it be dangerous to plug this into a device that does not expect to be powered?

No moreso than using a USB-A to USB-C cable, unless I fundamentally misunderstand something

Doesn’t USB-C deliver more volts and amps?

Reminds me of issues I had with the Wahoo Elemnt Bolt bike computer:

For some weird reason it cannot charge if you plug the other end of the USB-C cord to a Apple made charger. It works with all other USB-C wall bricks.

Never understood what that was about

I don't think anyone is expecting them to release a new revision for just this change. They are just asking that the next revision includes this fix with the other changes that would justify a new revision anyway.
