Uses many of the same algorithms as wma...

Not codecs, these are raw formats.

Is arithmetic coding still patented?

Again, not codecs.

No, if you don't count the raw formats there are essentially no codecs
that do not have _claims_ of patents. The few that do exist do not
achieve any significant compression. Boycotting some formats which
have claims of patents against them while praising and promoting
others which have EXACTLY THE SAME status is doing everyone a
disservice.

No. He told you to DISABLE EVERYTHING, i.e. build a ffmpeg that DOES
NOTHING! This is the only way you will ever avoid patent claims until
nonsense software patents are abolished. Even the simple XOR operation
is patented!!
