The document in question mentions them having over 4,000 managed properties, assuming an average of $1,000/month for each one of those, across the 2 years between October 2012 and now, that's $96,000,000. I seriously doubt $600,000 is enough to make the venture unprofitable.
Even if I'm off by two full orders of magnitude it'd still be $960,000, and it's possible I'm undercutting the truth.
It sounds like they were only blocking connections at one specific property (Gaylord Opryland Hotel and Convention Center in Nashville, Tennessee), which changes the math a bit.
Also, don't forget the cost of doing compliance audits across all of their properties for the next three years, which is not going to be cheap either.
I think $600,000 for this incident makes the net venture still profitable. I'd bet that $1,800,000 for each future incident (assuming treble damages because they'd already been penalized for this once) would make it very unprofitable very quickly.
