Can someone explain to me the people still wearing a mask but wearing it around your chin or under your nose. No one is asking you to wear it
I do. The law still mandates it, almost everybody in the major cities still wears one, and I feel that walking without one can be seen by others as a lack of respect to accepted norms, therefore a chilul hashem.
The logic is also simple, if you have a mask on your chin you're much more likely to raise it when encountering other people. I walk outdoors a lot and it's very common for people to raise their masks as they come closer. A large part of the reasoning for the outdoors mandate was in fact that it would lead to people wearing it indoors, which is much harder to enforce on its own.
