So? This isn't taking advantage.

There is nothing in the these war fare rule relaxation that says you have to be scared of flying to a particular place for some reason related to the war directly.

The airlines instituted this policy because of the steep decline in traveling during this time. That's it. So I don't see what you are doing as exploiting anything -- you are traveling when many people are staying home. That is why the airlines are "rewarding" you with the fare rule relaxation.
