MP3 decoding was already free and got recently included in Fedora. But now, encoding is also free according to Fraunhofer Institute for Integrated Circuits IIS: "On April 23, 2017, Technicolor's mp3 licensing program for certain mp3 related patents and software of Technicolor and Fraunhofer IIS has been terminated." The Wikipedia MP3 article confirms that.
So, do you still use an MP3 library or have you switched to another format or means of listening to music such as (spying built-in) streaming services?
Currently you have to jump through some slightly annoying hoops to get the LAME mp3 export library installed. I don't mind too much personally but it's not so easy to explain to less technical users, and especially since the links in the software lead to sites with instructions written exclusively in English...
Presumably this will not be enough to unencumber ffmpeg though...
