Google promising free license to anyone who implements AV1 would have been ok, if they patented something that is only useful for AV1. But they patented "using ANS for video" so now you can't use ANS in any competing video codec. In my opinion, people absolutely should fight to invalidate this patent using any work that mentions using ANS for video from a year (or more) before the filing.

I think you can, software patents don't work in EU, you'll have just trouble doing it in the USA.

  This is incorrect, you are conflating algorithm patents and so-called "business method" patents (e.g. "$BUSINESS_ACTIVITY using the computer/internet"). Proper algorithm patents are supported in Europe because they are equivalent to a novel electronic circuit, which is generally viewed as patentable subject matter.
