There is no credible theory to that effect. Either you have stumbled on something that is not taken seriously, or you are misunderstanding the consensus. Namely, Proto-Germanic speakers did visit the eastern Baltic coast for trading and raiding, and so there are Germanic loanwords into Finnic languages of Proto-Germanic date, but the agreed location where Proto-Germanic formed is in Scandinavia, not Finland.

I'm not sure you have a good grasp on the meaning of the word "recent". A recent theory, by definition, must differ from the consensus.

Granted, they don't say "Finland". They say "the northeast along the Baltic coastline".

		Yes, I’m afraid that you are still misunderstanding the research. Your linked article speaks about gene flow associated with the movement of pre-Proto-Germanic speakers to Scandinavia, but later Proto-Germanic formed in southern Scandinavia according to the longstanding consensus. This is clearly spelled out in the abstract: “Following the disintegration of Proto-Germanic, we find by 1650 BP a southward push from Southern Scandinavia.” There’s no new theory here at all, just some nice archaeogenetic evidence to support a quite traditional view. FWIW, I work in a closely related field and am constantly reading Germanic–Finnic and Baltic–Finnic contact literature, and I can assure you this is old-hat stuff.
