I say the EU makes a list of categories that you are allowed to categorize users in:
- Age (only year, no month or day this is not relevant).
- Sex
- City or geographic area with at least 500,000 people.
- 5 items selected from a list of hobbies / preferences..
etc.
Companies should simply not be _allowed_ to target people based on categories like being ill, being poor, being terminal, being depressed etc...
And here's the kicker: if every company is held to these same standards no one company has a disadvantage.
Well, except the entire ads industry scene which is now set in anarchy.
