You don't know that for sure. On the other other hand we do know things, like without the open source ethic Wikipedia wouldn't exist.
An example: Pfizer closed down their Lansing michigan plant and wanted to force their employees to relocate to San Diego, without doing a real analysis of the decision, and on the eve of the move came to find out that the one person running their fermenter culture system didn't want to move - he wanted to raise his daughters on a farm and San Diego was too expensive for his pay grade. So they lost the ability to basically do every bioassay that they were doing in Lansing. Three years later, I had the opportunity to work next to the massive san diego pfizer campus. The facility was 2/3 empty and pfizer was struggling to find extra tenants and toying with a 'bio-incubator' idea.
