That's because in the beginning there was no scientific evidence that it would help, but as they discovered the matter in which it transmitted, the recommendations changed.
They also had a shortage of medical PPE, which you fail to take into account. They wanted to make sure the medical professionals had what they needed in order to safely treat people with Covid-19.
That is how science works. Further information can change how you deal with things. Theories and hypotheses change as more information comes to light.
How did you not know this?
Anyone CAN have it, as some people are asymptomatic... meaning they won't show symptoms.

There is no justification for not wearing a mask, as masks don't reduce oxygen intake, in any way. It's probably SAFER for people with asthma to wear it, to protect them form allergens and pollen. Doctors and medical professionals often wear masks all day.
I worked at a manufacturing plant where people wore N95 masks all day. Even those who had asthma.
I don't know how autism would affect this...
