I doubt it's operation because when in 2007 I asked myself...
That wasn't the question. The question was what physical law prevents the nickel porous plate sublimator from working. You are a degreed engineer, questioning an engineering item. You can -- and will -- be expected to provide an engineering rationale for your claim of its non-operation, complete with any quantitative computations and citations to standard references.
You were not asked simply to repeat your claim, which has already been debunked as your obvious ineptitude at research. It is quite obvious that your conspiracy theory is motivated far more by your desire to be a hero than by any specific, articulable scientific fact. You don't get to accuse NASA of being unaccountable when you are unable to account for your accusation by means of a scientific proof. Simply whining that you couldn't find information on the internet is inadequate, lazy, and unprofessional.
I argue that it's preposterous to expect an astronaut to wait...
Asked and answered. You demonstrate no competence in aerospace training and testing. Your opinion over its propriety, as conducted by those who
are qualified, is therefore irrelevant. Alluding to your also-debunked claims regarding the ISS does not salvage your overall argument from ignorance.
I'll admit that this whole "immoral" argument has taken me by surprise.
Indeed it has. It's obviously an aspect of your long-standing, often-repeated dog-and-pony show that you have not yet faced. However, mocking it does not refute it. Nor would various state authorities agree that you are an authority on what is moral. You are clearly unable to deal with its effect on your claim that the test you propose would be a necessary and prudent step in validating a sublimator for space -- a goal you insist on conflating with personnel training despite several attempts to explain to you the difference.
I probably have one of the cheapest cellphones on the market and it takes great photos and video.
Try to get it into a secure NASA facility. Especially
you try to get it into a secure NASA facility.
Further, you were asked several times why you consider photo and video credible evidence of a human space-suited astronaut in a vacuum, cooled by sublimation, when you dismiss already-existing photos and video by speculatively claiming the vacuum (or some other aspect of the test) has been faked. Your inconsistency and evasion in formulating the test you say is essential and probative reveals your ploy simply to be constantly moving goalposts. You're demanding a specific activity that you know will never be undertaken, simply so you can get rhetorical mileage of complaining that it won't be.
And why are we having this debate?
Because you want attention, and are willing to stoop even to criminal activity to get it.
Fundamentally, it's because NASA refuses to be accountable.
NASA is fully accountable to the extent it is expected to be, and to an extent you simply refuse to acknowledge. Without any justification, you simply want their accountability to include acquiescing to the demonstrably ignorant demands from a single crackpot. You are simply not that important.
...and most of all allowing independent witnesses to observe spacesuit with ice sublimator testing or training in a high vacuum chamber on Earth duplicating environmental conditions of orbit.
Asked and answered. Your argument for the necessity of that test is predicated entirely on your delusional denial, which no one else shares. Your argument for the practicality of that test is predicted on a colossal level of ignorance for what it would actually entail. You have addressed neither of these objections, except to state and restate the same ignorant beliefs. Further, you have assiduously ignored every other form of documentary, eyewitness, and circumstantial evidence that has been placed before you, and which serves to convince
literally the entire educated population of the planet that space suit cooling works as advertised. You have sought to assuage that unanimity by claiming that everyone except you is a coward for not agreeing with you. That is not persuasive.
