"But Microsoft can still influence how things go from here on.
If they have to live with open source, the Apache project is
Microsoft's preferred direction. Apache doesn't use the dreaded GPL
and its enforced sharing of source-code. Instead, the Apache
license is practically a no-strings gift, with a weak provision
against patent lawsuits as its most relevant term. Microsoft can
take Apache software and embrace and enhance, providing their own
versions of the project's software with engineered incompatibility
and no available source, just as they forced incompatibility into
the Web by installing IE with every Windows upgrade."
