# Financing free Software
Free software is hard to fund,
because selling software isn't
really possible.

Due to the fact, that
users of the software
are granted the right
to modify and redistribute
the software they bought.

Which makes the selling
of software itself rather impractical.
Not it is impossible, [Threema](https://threema.ch/en/) is a
popular example of free software,
that is being sold.
Although they only published
the source code after they got
enough financial backing, that
the risk of clones of their software
was less important.
