As far I know is this outdated info, expired. And were subject to patents in certain countries.

For example the IDEA patents have expired in 2012 and IDEA is now patent-free and thus free to use

See also in the readme of the binary.zip:

You are correct that IDEA is no longer an issue, but the RC5 patent does not appear to expire until March 3, 2018.
