I know you wrote H and O, and not H2 and O2, but I’m going to assume the gas forms because those two substances pretty much cannot exist in their pure forms
And for those, O2 is necessary for our life, and H2 is non-toxic, it’s just very flammable. So I don’t know if the comparison fully works
Of course, you’re right if you mean pure H and pure O, but, again, they will immediately combine to form a new substance
Frankly, governments should always have gone full Linux. Or other FLOSS alternatives
I see no reason for preferring corporate controlled services, especially by corporations not in your jurisdiction, to FLOSS that you can have full control over, and in the worst case can take over development or help direct it
