So you are a victim ! π
I assume if I were to click on the 'buy' button it wouldn't pay you one cent !
Complain to them directly.
They are blatantly stealing.
If they sell a product without its author's permission, and don't pass on the money it's plain wrong !
Also complain directly to Trimble.
If they do not have an agreement to sell SketchUp in Poland then Trimble will take a dim view of this.
If they do have an agreement to sell SketchUp in Poland then Trimble will take an even dimmer view of them pirating other related products.
If they are based in the EU [Poland?] then they ought to be subject to some laws about 'counterfeiting' etc π²
