Making a profit does not equate to success.. How you go about it matters. Profit via "abuse" of power does not make for a "successful" company, accepting that what constitutes "abuse" is subjective.
So arguing for striking the right balance would be valid, calling any regulatory step a "penalty" isn't.
Ultimately "successful" companies require regulation to serve the ultimate purpose of any and all laws - the wider good - for humanity and society.
No monopolies is what I say. Yes if you are that successful, you're too successful. You're eliminating competition, instead of competing.
The wider good takes over and laws must ensure this. A free market cannot function without competition - it is designed to only work with it.
