There is a difference between understanding the content (e.g. ICO) and understanding what happens a few weeks after the content is interacted with (e.g. someone runs off with the money). The first is doable, the second requires prescience.
Every Facebook ad has a dropdown in the top right corner, and one of the options is "Why am I seeing this ad?". It will show you details on that ad's targeting and why you are seeing it.
At least in the United States, Personality rights are only for commercial use. You do not need someone's consent to take their photo or to publish said photo as long as you do not attempt to profit from it.
This for example allows you to take a photo on the street and publish it even if the photo contains some strangers. The concern that does come up is whether the subject of the photo has a reasonable expectation of privacy; if they are in public, they do not.
(note: not a lawyer, but I have taken many photos of strangers)
It's not about individual productivity - it's about team and company productivity.
I doubt anyone questions whether individual effectiveness suffers from an open layout. However open layouts have several benefits that more than compensate:
- Impromptu conversations are easy. The barrier to ask someone a question is lower - it's faster to get unblocked.
- Shared context. With conversations happening in the open, others will often overhear, sometimes learn, and often will choose to participate.
- Impromptu socialization leads to better morale. Someone drops by to chat socially, others join in, people build personal relationships.
- Function-specific spaces. The space saved by having a denser desk layout is allocated to having everything from kitchens to massage chair rooms to ping-pong tables. At the same cost per employee, an open space layout has more 'perks'.
I've worked in both offices and open spaces and I far prefer open spaces with a good etiquette about when to interrupt someone.
