Bollocks, WAV - you don't like it because it doesn't fit into your racist scheme of ethnic & cultural stereotyping & segregation. The Irish bouzouki is a recent development, but already it is very distinct instrument from its Greek antecedent, just as the Greek Bouzouki is a very different instrument from the Turkish SAZ from which it derives - see Here. Everything was recent once upon a time; like the plethora of Arabic reeds, lutes & zithers brought back by the crusaders that became an integral part of European music thereafter. The English Cittern (as invented by Stefan Sobel) is recent; likewise the Leicestershire Bagpipe (as invented by Julian Goodacre) - both are based on old notions perhaps, but very much modern non-traditional innovations that have found their way into this thing we call Folk Music, which is also a pretty modern innovation; a renewal via a revival of something which barely existed 50 years ago.   The Irish Harp is a bit of a reinvention too, likewise the Union Pipes; all have very clear points of origin & hybridisation that run entirely contrary to your impossibly misinformed and entirely specious notions of the indigenous.

You know so little, WAV - yet you judge so much. More learning I think; more listening instead of preaching; you really are in no position to make these sorts of judgements. No one is.
