“Successful open source packages need accompanying commercial
efforts to ensure their mainstream adoption.”
“The combination of free and commercial developments makes open
source software a formidable competitor in the software
market.”
“As an open source package becomes more and more popular, a
widening gap develops between the needs of the user community and
the features provided by the core developers. Sooner or later,
commercial ventures will form to fill this gap. The user community
will demand the additional services and offer to pay for them, so
the business opportunities eventually become irresistable.”
