This seems very one-sided and does not address real issues. If you don't address key issues around expectation setting, common goals, etc then yes these may occur.

Similarly, claiming that open plan offices put people under fluorescent light away from windows is specious at best. The typical 'old school' office set up had offices around the perimeter (ie windows) and kept everyone else shielded further from the windows.

I am more interested around what design works in open plan? Or, does open plan actually make you more sedentary because you don't have to walk to your colleagues.

I can see some of these examples being an issue, but some can be easily adjusted. I also think it depends on the type of business.
