That's not what the article and a lot of commenters here are saying though. The article makes vague insinuations about "corporate gambling".

If you're just targeting sports books I think other than the folks making money from the industry, you'll find few fans. They offer predatory parlays with often outright negative EV or very high variance returns. They kick sophisticated money out they can find edges. They leave no room for above board players like market makers providing liquidity through efficiency.

I think a better article and discussion could emerge from just tackling the harms of sports books.
