Perphaps if more people would invest their time to play with dice simulators for a while, to see how martinagle really performs, and how "hard" it is hit a streak of 10+ losses.
According to the wikipedia page, martingale originated from and were popular in 18th century. I am sure many gamblers have seen for themselves how martingale is bad in the past 300 years, but it remains popular and still is considered to be a good thing by many. Considering that, I don't think martingale players will change their mind with simulators.
A lot of people that think martingale is legit are just casual gambles or newbies that have seen it in some movie, and they think they can suddenly become George Clooney in Oceans 11 and start racking up mad gains on the casino, but if things were that easy we would be all rich already, and that's not how it works.
