Which is something I think deserves a bit of context. It had been the Finnish air force's official insignia since 1918, so it was unrelated to the German Nazi Party, although of course that association was inevitable once they seized power.

Similarly, the stone elephant holding the gate building to the old Carlsberg grounds in Copenhagen bear huge swastikas on their sides, since they were erected in 1901:

There are a lot of swastikas still present in old sculptures and designs with no relation to nazism.

I think that was explained quite well in the article, and while the symbol has had a long history I think it is fair to say that these days the majority of people would see the symbol and think "Nazi".

Removing it feels like a reasonable thing to do, though I'd probably draw the line at chisel it off old-buildings, etc.
