What's your point? There are lovers and haters of every opening. Despite the fact that I don't care much for the London at all, I'd rather play 100 games with the London, 50 with White and 50 with Black than to play a single game with either color in a Grunfeld or Alekhine if that tells you my level of hate and distain of openings that involve the mobile pawn center. I'll take any opening that results in a closed, open, static, or dynamic center over the stupid mobile pawn center.
That said, I know others that hate the blocked center (French and Kings Indian). Everyone's different. So to single out the London with "Many people" is ridiculous.
Many people hates london system, and some loves them, lets start of with london system
