If the NBA added 6 new teams in an 8 year span which coincided with LeBron's prime, shortened the 3 point line to help LeBron's score more, and instituted a new rule (flagrant foul) to make it harder for LeBron's opponents to play physical on him.

Would LeBron haters complain?

this is literally what happened for MJ. People either don't know or ignore that he cried to Stern to create the flagrant foul before the 1990-91 season bc the big scary Pistons were pushing little Mikey's shit in for 3 straight years.
