That reason is nonsense because they will meet in the semi-finals anyway, not in the quarter-finals. I am definitely in favor of the second option because the first option was adopted after the competition had already begun, which means it cannot be correct.
You cannot re-draw the maps. I believe that changing the draw during the tournament is unacceptable, as the reason described above is not that important; they are not playing for 1st and 2nd place in the groups, but only for 1st and 3rd, which means the stronger 1st and 2nd will not meet, and everything is fine.
Changing the draw during the tournament sets a bad precedent and will affect your future tournaments. If you didn't like the draw, you should have said so before the competition began. I ask the judges not to give in. Show principle and do not change the rules during the competition. Or, if the herd instinct has already kicked in, as was written above, conduct a re-draw after the group stage. A final one, although I would not change anything.
