I was't clear over your roules, jaclaz, I have supported bigmuscle since early -13 and OC I use a key on my machins, except for my windows 10 insider machine. Uptil mid dec-15 when it completly broke down, (since it won't update any more). After a clean install of w10 I decided to end my window insider roll, bc it did't make any sence to go on really. But under those 13-14 mounths I did't use any key and did not have any problems with BM watermark on my lower right corner ( for a long period windows watermark was there as well..... So whats your point, really?
