Dropbox has 2500~ employees, and obviously this is just an anouncement. In some years we will have a clearer understanding of the tradeoffs.

My suspicion is that companies that will fully embrace the "internet way" of doing things will have success.

It's not a zero sum game. WFH can simultaneously save money for the company and for the employees.

The complaint is the distribution of that savings particularly in a highly leveraged scenario like COVID. Employee power is at an all time low.
