Don't be naive. They definitely are Russian backed acts. Not all sabotage is done directly by their state security apparatus, funding useful idiots has been the Russian modus operandi since the Soviet times.

lol come on, I'm German. Of course a lot of the terrorism was probably (Vulkangruppe) or proven (the DHL and airport incidents, Tiergartenmord, SUV Bauschaum) Russian.

The only thing that is probably something else is that guy from the last week shooting wires over transmission lines (lone wolf ecoterrorist), and the Nord Stream explosion which likely was Ukrainian.

Anyone blathering about "the far left" is probably either far right or a Russian shill.
