The link in the submission is saying that the representatives position is mostly unknown for all the Baltics (Lithuania, Latvia and Estonia).

For Finland it says only 3 of 15 have opposed - which is clearly not a majority.

The “assumption” based on government position has no reference to any stated government position (I know for a fact Lithuania have expressed no such opinion, and can’t find anything related to Latvia or Estonia having done so either) - and also “assumes” all representatives (that are from different parties) are aligned, which they most likely aren’t.
