I get the limitations on manufacturing, costs, margins, etc. But they could just advertise it for 10E, sell it for 10E and actually make a profit that they can use to improve the product, drop prices later, etc. If I end up paying 10E anyway I'd prefer it if the ad didn't tout "Only $5". It's misleading no matter how much I like the company who's doing it.
edit: found the announcement: https://www.raspberrypi.org/blog/raspberry-pi-zero-w-joins-f...
But this means the original Zero was marketed at $5 which was still never the case where I live (10-20E was/is the norm, maybe courtesy of the shortage). This being said I bought them either way. It just felt a bit disappointing when the expectations set by the promotional material weren't met when ordering the product.
Now imagine a fixed configuration car being sold at double the price. Car ads usually have a fineprint “config used in the ad includes bla and bla and costs this much”.
Where it is like the car industry is when they advertise fuel consumption or emissions numbers that are never achievable in real life. And in that case I feel the same.
People who complain about the cost making their projects difficult should speak up about the alternatives they’re jumping to instead.
