the oxygen is found IN the coma surrounding the comet by the Rosetta orbiting the comet
not by the lander ON the comet
so there is no confirmation that this oxygen is coming from the comet
being a charged body flowing through space
it is likely that the comet is attracting the oxygen (and all the other gases) to it
(a giant "static cling" mop sweeping through space)
Yes, various articles make clear that the oxygen was detected in the coma. Do you have a source to support your outlook on where the oxygen is coming from?
