Microsoft is planning new negative comparison marketing, starting with
Linux, Apache HTTPd, and MySQL, most likely reminiscent of their anti-OS/2
campaign.

Another way of looking at it, however, is actually good for Open Source
supporters. The man in charge of the project at Microsoft, Martin Taylor,
says that the "the end-to-end scenarios is where things don't work quite as
well with Linux." But that is precisely where Open Source consultants and
integrators can find the Value Add proposition. That is where Open Source
differs from Free (as in money). Someone needs to provide support,
integration, deployment, enhancement, etc. Companies can either develop
that expertise in-house, or out-source. And in the longer run, Open Source
projects will evolve to make such tasks easier, as the lessons from
deployment are fed back into the development community.
