Again, they're selling products worth nearly $2000. I'm not talking about changing their production line. I'm talking about why this happened in the first place. You said it was to save money because "adding extra chips is not worth it". I highly doubt it. This appears to be a design error. A design error while saving money on engineering? Maybe, but that isn't what your first comment said.

C'mon, dude, we're talking about SMT resistors, which I'm sure are already used elsewhere in their design. If any electronics company in the world can't "secure" a supply of SMT resistors, we have much bigger problems.

I agree that doing even a small redesign of something existing isn't free, but every company comes out with new designs for new products or to make an existing product more cheaply. At the very least they could acknowledge the issue and put the fix on the queue for the next rev of the board.

My guess is that the support person didn't actually forward anything on to any engineering team. At most they sent it to their supervisor, who told them to just make OP go away.

That’s to change it. There would have been no additional cost to do it right at the start other than the resistors.

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.

You apparently have no idea how electronics are manufactured.

There is no such thing as "changing the whole production line".

Also, the marginal value the additional components provide exceed their costs by such a wide margin. The ROI is easily in the 10000%.
