Again, Oda can't adjust for "backlash" within a 1 chapter timespan. This chapter was already done. There is also no proof of offpaneling
He didn't adjust it in one chapter, it has been the plan/structure of the fight between Kaido and Scabbards all along. He showed the beginning of the fight, the he will off screen the middle of the fight, and will come back at the end of the fight.
And also, very few people are "not happy" with the main villain treatment. Its a vocal minority that doesn't understand that Kaido will eventually wipe the floor with these characters. Most people understand this.
