In general, but not in specific. Saying that a specific practice should be illegal is productive. Saying that a particular company is bad is not - they'll simply say, 'we follow the law'. And they'll be right. Then the politicians will say, 'you can't ban Amazon'. And they'll also be right, because laws can't be targeted against specific groups. If you target specific techniques and practices (for instance, child labour, historically) then the supporters and lobbyists have to actually justify the problematic stuff - they can't just hide behind the nebulous vagueness of all the things big companies do.
