It seems that some people really are cheapskates, although in this case they may have got what they deserve.
From a post by Mike Simpson on UKTS;
I am seriously considering ceasing all work on RW_Tools and removing it from circulation.I have found that there is a crack for my program on the web (to be expected), but when I saw that over 170,000 attempts had been made to download it, as compared to the 10,000 or so who were willing to donate a minimum of $2 (or 1 quid), I got really p....d off...As downloading the crack in question does load malware on the downloaders PC, maybe I should not have said anything, but now I know why there is so little 3rd party rolling stock for TS2015, no one wants to pay anything for it.Mike
Yet again it seems that a small minority of lowlifes could potentially ruin things for the majority.
