I believe the fundamental problem that these companies face is that they've grown so big and complex that many fiefdoms have developed. There are isolated teams within the larger organization. Frankly, it doesn't matter if the teams are in the office or working from home. The Real Problem (TM) that they're facing is that they've forgotten how to innovate, communicate internally, and be agile at scale. They want a quick fix for these problems, so it's an easy mental leap to "get everyone in the same building to start with." The "no more telecommuting" is making headlines, but what isn't making headlines is whatever else they are doing AFTER the telecommuting is over to fix these problems. I certainly hope that if "all hands on deck" is Step A that there's also steps B-Z. The real problem is if they think ending telecommuting will solve all of the real problems. (It won't.)
