Why

Why
Trust the
source
Gain from
community
Build
bridges
Reach
other
markets
Everybody
else is
doing it

Why
Trust the source: companies will respect more a package if they can
see what’s inside and even change it
Gain from community: attract respected developers from the open
source communities; have others fix bugs and contribute new
features
Build bridges: join communities with similar concerns together
Reach other markets: sell software to other platforms; profit from
support
Everybody else is doing it!
