The scandal that is unfolding right now regarding Facebook and Cambridge Analytica is not about only about how data is shared without the knowledge of users (the quizzes and other means to gather information did not say for example that the data will be used for election campaigns) to big companies but also of an industry that has worked unchecked for years.
First off, both companies and mainly Facebook are being criticized because the first gave off the data of about 50 millions users to Cambridge Analytica in order to help President Donald Trump to win the election of 2016, which he did (was the win solely work of one company? highly doubtful). The problem is that this kind of practice is neither new nor will go away.
Political consultants from the US and of other countries like the UK, France, Germany, Canada etc. work all around the world for decades influencing elections. Individuals and companies are hired by major parties from Africa, Europe, Latin America and probably all over the world in order to tilt the scales of power towards them.
So what Cambridge Analytica has been doing is taking this already established industry and using social media and the so called big data in order to service its clients in this case the Trump campaign. An industry as extensive as this is only natural to use the ever alluring pool of personal information, that we should not forget the users themselves agree for their data to be used (for example if you are on Facebook and you press one of the many quizzes you have consented for your data to be used by someone for some purpose).
If this case serves as a basis for an unethical industry to be reeled back then that will only be positive for the many countries that are on its clientele, if not then scandals of this type serve other purposes that are of no interest to any citizen of the world (only to remind that technology and political power has many traps).
