Apparently it looks like some of the I1 in Sweden (particularly in east Sweden) is of Finnic origin and most of the I1 in Finland is not from Sweden.
They are distorting Nordtvedt's conclusion (of course full of personal nationalistic creep agenda). Nordtvedt just posted
some of the I1 clades in Finland pre date for more than 3000 years ago. And nothing more.

What is truth. However, its origin is still ultimate Scandinavian, like it or not. Obviously, these (Bothnian) mutations that then happened there were, of course, Finnish. No doubt of that.
Possibly according professor Nordtvedt's last conclusion, some of I1 in Finland went there via Scandinavia during the pre-Bronze age. Movement of people, including Scandinavia, the Isle of Gotland and Finland has always existed for more than 4000 years ago. It is already well known among the Swedish, Danish and Finnish archaeologists.
Finnish professor T. Lappalainen also said it in 2009:

Apparently there appears to have been several times as much movement from Finland to eastern Sweden than the other way round throughout history and prehistory, this correlates with the levels of N1c in eastern Sweden and also people working on I1 have apparently changed their minds based on the evidence and Bothnian clade is now older, making I1 a movement from east to west:

The movement of people in the past, (pre-historic times, Bronze-Age, and Iron-Age (Viking era)), was more from Scandinavia to Finland. In recent times like from the 17th century (Finnish forest immigrants in Sweden) and the industrialization of Sweden in 20th century, it was greater from Finland to Sweden.
I1 in Finland is close to 28-30%. (depending on the source.)
N1C in Sweden is close to 10%-12%. (depending on the source.)

And the presence of
some N1C clades in Sweden date over 3000 years ago. Through some pre-historic migrations via the 'Baltic countries' to the Isle of Gotland or via Saami in Northern areas. They are not necessarily all of resettlements by Finns.
