If I understand it well, @cervantes is not criticizing all those who make mergers but we must be alert to if the mergers are made for the right reasons.
If they are done because it will be better for everyone, I do not think anyone is against it, it is another thing that is done with bad intentions or that the only beneficiary is the one that fuses the asset.
Personally for me it would be more correct if an asset does not work cancel it by repurchasing the shares that make rare mergers
