Not at all! Today at a Remembrance Service my wife and I wore brooches produced by a local veterans' charity; a poppy superimposed over a local landmark. No connection with RBL.
You could also make your own, wear a real poppy or buy a diamond-encrusted brooch from the likes of Bradford Exchange, if you're into bling.
The RBL have a trademark on one particular pattern of poppy emblem ( two-petal, with leaf ); that's all.
