I'd ban all advertisement and put a market cap on these companies before mandatory breakups happens.
None of these companies should be worth a billion dollars.
My big fear is these companies are all getting rich which means they'll be able to buy political influence.
I'm pretty tolerant of a lot of vices. I also don't really have a problem with low levels of gambling. But the way these companies are setup is just sick. It's abusive the the public and erosive to society in general.
