Yeah I've read all that. It's a joke right? You attack the use of soap? Bicycles have been around for a bit over a hundred years... and whether or not animal fat is used in making the soap/detergent... the bicycles have been washed. I have been washing bicycles for half a century myself... and I haven't seen ANY of that "wear and corrosion" you think might happen.

Almost everything has both a common AND a chemical name. Roses and soaps... remain the same whether you call them by ether their common or proper name. Citric acid... can be BOTH a harsh cleaning agent... and part of the tart taste in my lemonade. Yes... there has been "environmental and health concerns" about washing.... forever. But I certainly wouldn't call those concerns "growing". Proper hygiene has pretty much "caught on".

Modern cleansers rinse away easily and break-down/degrade pretty darn quickly. Your fears about using common dish soap... do nothing to effect its usefulness. Even if you use petroleum solvents to clean/remove the gunk... you then need to remove the petroleum solvents with a soap/detergent. Your not leaving the solvents on the bicycle after its evaporative agent dissipates are you? So ether way... you need to break-out the bucket and sponge. Why make cleaning a two-step process when using soap to begin with is faster, cheaper, and does a better job?
