Open source - Free software

[v4vijayakumar]

I have been using "open source" and "free software" products for some
time. I want to contribute to them but I couldn't decide between "open
source" and "free software". I would support "open source" at this
level, because we can see what it is doing. I don't know how many of us
can really see the things, but we have some issues in using "free
software". Consider a "free software" web client (browser), it would
comfortably send the confidential info to the person who programmed it
that way.

Expecting replies this way.
x : y

Where,

x is either "Open source" or "Free software", without quotes

y is a statement which supports x to be chosen and it can not be more
than 80 characters in length and, 1 line in height

I hope to get all the replies this way. No fun intended. :)
