In all 3 of these videos Hikaru heavily criticizes Ding for poor opening prep - i.e. spending 30 minutes on early moves that should have been in the WC prep, playing lines as white that aren't testing... etc. And these are just the 3 I watched, I didn't even watch the rest. Your response just dismisses / ignores anything Hikaru had to say in order to affirm your preconceived notions / ignorance. You're not a serious person.

(...) the fact that Dings prep was lazy, I've already acknowledged multiple times that it could make sense to play for a lazy person - again, not merely my opinion, it's an opinion Hikaru himself voiced. Considering how much prep is needed to play the WC there is some motive here. And the London also sidesteps so much prep, which is another advantage when you're crunching a set of new lines for a specific tournament. Again a lazy mans solution which wouldn't apply outside a tournament setting.
This is also complete nonsense. Ding was so "lazy" that he prepared multiple openings for white, as he opened e4, d4, c4 and Nf3 in various games.
Hikaru was probably just trolling, creating drama for clicks.
