There is a big difference; using this system you could directly facilitate the distribution of data that you do not want to be associated with.
Buying a camera doesn't directly help the creation or distribution of info you consider to be immoral or unethical. Obviously you may want to use a camera maker or ISP that actively discourages such behaviour.
I'm sure you would feel extremely guilty if someone used storage facilities that you controlled to spread CP. On the other hand, I've never felt guilty about buying a camera as I've never let anyone use my camera for such purposes.
But this system doesn't allow you to distinguish between files. You either use the whole thing, or don't use it at all.
In the camera example, you have the option of not letting people use your camera your nefarious purposes, which isn't the case here. It's more akin to supporting the camera manufacturer, who, in turn, makes things that might be used by people for crime.
Even the most ethical manufacturer uses raw products down the line that in some way have passed through unethical processes. Consumer choice and vocal dissent is only one part of the equation, the other is active support of prevention and awareness programs.

OK, interesting. I guess it's a personal thing. For me it's not just a question of whether I know or not. I also have to consider if there is anything I could reasonably do to prevent such things from happening. If there isn't, then I would consider whether I really need to use the system (for example, is this my only option because I live under an oppressive regime?).
I think this was the point of the GP asking, "How do I not unwittingly get CP being stored on my device?".
So you wouldn't work on a company like Dropbox or any other of those file storage systems? Or a VPS/cloud provider? Or an image hoster?
And what about physical things? If you're working on a retail job, the customer buying piece of rope may be planning on using it for tying people up. The guy renting a car may be planning to use it on a hit.
Ultimately, it's not possible to keep track of everything people do with the services we offer.
Lots of people have no sense of guilt whatsoever. It's not a good thing, but with an enabling community saying "it's not your fault" it's awfully easy for people to pretend there was nothing they could do.
If he _actually_ cares about the children he'll do something about it, like acting against child abuse in his community, rather than caring if CP is somehow encrypted in data located on his computer.
