The demise of Cambridge Analytica hot on the heels of the latest Facebook privacy scandal is, let's say, unsurprising. The firm has served its purpose. Its day done.
Call me a cynic ("Gary, you're a cynic!") but I'd be amazed if this was anything other than an attempt by the company owners and managers to bury the bad news and move on. Will their continuing and future business activities be any more ethical and appropriate? We shall see.
As long as there are paying customers, businesses will continue making money however they can, as they have always done. Whether you and I consider their activities legal, illegal or in the twilight zone doesn't particularly matter to them. Profit corrupts, obscene profit corrupts obscenely.
