excerpt from wikipedia synopsis:

>Arnold organizes a demonstration of the hosts to convince Logan to invest in Westworld. Logan's father, James Delos, is critical of his son's actions until William persuades him that the park can be used to spy on the guests. James proceeds to buy out the park and name William as his successor.

That was coincidentally about the point I lost interest the series as it totally jumped the shark from “flawed but I can suspend disbelief” to “oh great, another series that’s going to build ever more tenuous conspiracy theories”.

Not really clear to me how spying on someone's sexbot vacation is a viable business model but ok.
