This shouldn't disqualify the RPi, in my opinion. We're moving incrementally towards a world of open firmware and open hardware from a totally closed world. It feels like we're making forward progress. We shouldn't punish incremental steps on this path, nor should we stop asking for more open hardware.
That's a pretty big difference.
All this means that people serious about a product have to avoid a RaspberryPi, and this is terribly unfortunate because it has such a wonderful community.
This feels like a dramatically different category of thing than what the Pi is, to the point where comparison starts to get less meaningful.
But frankly I'm not sure the RPi folks should give a damn. They're selling whole computers. That they don't fit into someone else's product pipeline is unsurprising.
It's like complaining you can't turn a MacBook air into a blade. It's true, but it's also a bit wrong to expect you could have in the first place.
For who?
If I want to deliver a quarter million of these I can't.
The whole point of Raspberry Pi is to provide a convenient SBC for people who don't have those engineering resources. If you're somewhere in the middle, there's the Compute Module.
Complaining about this is akin to complaining that your VW bus can't tow a house.
Remember that boards like the RPi are either loss leaders for the SoC vendor, or a way to offload excess capacity. Their pricing does not necessarily reflect what an actual customer for an actual SBC product will pay, regardless of scale.
A competitor who doesn't worry about such details will have an advantage in many markets.
At one time, the denizens of a site called "Hacker News" might have been expected to grasp this idea intuitively.
The post they responded to said that the Raspberry Pi is unsuitable to all "real products" because they can't buy 250k of them - you might actually be arguing against their definition of "real product"? rhinoceraptor merely pointed out that that isn't the goal of the Raspberry Pi, and one thus should use something else if it doesn't fit the requirements. If that's your situation, your competitors will have the same problem. If it isn't, then "use something else" doesn't apply to you.
They are used in industry already (digital signage particularly).
But as others have said it is not a problem as far as the Raspberry Pi foundation is concerned because their primary mission isn't to produce a board for use in commercial products.
For similar systems in quantity, a guy I know used toradex
Can I buy the chips? Can I get the technical documentation?
If I can't build my own RPi in volume, this is STILL a problem.
