* Conclusion
** On Flash
Flash is not actually secret but adobe keeps making new versions which
are different, faster than anyone can keep up and make free software
to play those files, so it has almost the same effect as being secret.
** On non-free formats
It's bad to distribute recordings in mp3 or any other proprietary
format. Although there is free software to handle those formats,
distributors legally can not include support for such formats because
they are patented in many countries. Modern distributions of GNU/Linux
facilitate use of these formats by letting the user decide, thereby
avoiding legal issues. Whether or not this is a good thing is a
question of moral. On the one hand, many of these formats have become
pseudo-standards and for most users, the short term usability aspect
prevails. On the other hand, it's a very bad idea if we were hoping to
get rid of proprietary formats eventually.
** Wrap-Up
- If you want to support freedom, don't distribute recordings in
non-free formats. Please use formats such as .ogg, .webm, or .png.
- In an epoch when governments work for the mega corporations instead
of reporting to their citizens, every technological change can be
taken advantage of to reduce our freedom.
