It seems to me that withdrawing from a tournament is actually a sign of respect for other participants, expressed by saving time on games that don't matter. What's the point of playing if it doesn't decide anything anymore?
Usually, when the results are tied, one of the criteria is the number of real and technical victories, and as a result, a withdrawal can ruin someone's position. In offline tournaments, withdrawals had a noticeable impact on Berger. Where is the respect in that?
