While fear of the unknown is understandable, to my mind the concern about open source specialists being acquired by proprietary vendors is driven by parochialism and misplaced assumptions about the rate of acquisitions and the acquiring company’s intentions.

For a start the statistics suggest that acquisitions involving …
