If you dont remember the saga began last summer when James Gunn was fired by Disney for some old tweets people didn't like.To which James Gunn also apologised for very publicly when they hired him on the 1st Guardians movie in 2014. The general reaction to the rehire this morning seems mostly positive. IMO he never should have been fired in the first place.
