For ADVANTAGES :
Think about all the functions that are being served (personal, social, political, economic etc.)
Think about the parties that are being served (consumers, the government, businesses etc.)
Think about direct & indirect as well as immediate and long-term benefits
For DISADVANTAGES :
Think about the parties that suffer some kind of loss (personal, social, political, economc etc.)
If possible, think about how certain functions that it was initially thought to have served, ended up being unachieved/unfulfilled
Know how some of these questions could be phrased :
XXX is as good as it is bad. What do you think ?
To what extent is XXX beneficial ?
How has XXX affected YYY / your society ?
