I don't think he is afraid of aqnything like you say,but let me explain to you why all pro tuners are against copy tuners.
A tuning tool or software manufacturer spends thousands of pounds or euros researching ,developing and producing a tool or software for a new car or ecu type and then sells it to a tuner to do the job.
Then comes along the thief that tries to disassemble the above and make clones to sell on ebay for £20.00.
How do you think the tool makers are going to stay in business to produce more new tools if they can't sell the ones they already made because they have been cloned!!!!!
Cloned tools never work properly,they kill more ecu,s than you can imagine,also pro tuners have legal tools to buy at high costs and a business to maintain to give the customer a proper service,hense higher overheads and higher costs,clone users, roadside pikeys and stolen software users have no overheads hence the 99p remapping charges(no backup or support though,either)
As for your winols,if its a legal demo version then it cant save any of the changes you make,therefore it cant be realy used to alter anything.If onthe other hand it does save changes then it is a clone and ILLEGAl.
