No, I don't even like the idea of people using dice that are "exclusives" much. If the dice seem to be as horrible as they are good, then it helps gain acceptance. If they are always rolling high, then that is going to invite criticism. At one point it actually got 2 people to go out and buy a block of dice in the hopes that everyone would agree to use them.
The most criticism that any of my dice has received were the official BT dice that came out the other year. "I can't see what the numbers are." Was the main complaint, well the only complaint received several times. But, when I'm calling out misses on shots that needed a measly 5+ to hit, it's hard for anyone to feel as though the design is helping me in any way possible, other then to hide just how horrible the rolls are!
Regarding RNGs, I know to much about psychology and sadistics to feel comfortable with them. Its not about not trusting the other person, its about knowing not to trust the other person. People will try to roll dice without declaring what it's for, then act like they were "getting the bad rolls out before making their shot", but next time they roll well they will declare a hit and act as though they did declare or forgot and if you don't trust them then you are the questionable one. I can deal with a lot of fresh fertilizer, but I want everyone at the table to not only have a fair game, but to also have the perception of a fair game on top of it. A lot of fragile egos, short child like tempers, and mistrust can ruin a game fast.
If someone rolls really well on an RNG but nobody declared or saw if it was a single button push then that opens a can of worms. Making sound when one pushes the button? Cute, but that volume can be turned down. Someone can "accidentally" tap it again while trying to show you the results. You might be able to trust someone with a grand sitting on the table, but not trust them to not panic and try to reroll. RNGs are flawed, but so are dice, right? Sure, but I can always have you use my biased dice instead, or have you swap yours out, or I use yours, but I cannot modify your RNG. I cannot modify the perception of a 3rd player by telling you to change RNGs, or reroll the RNG.
In the end its a lot easier to mess with an RNG result then it is to change a roll of dice that is observable by all parties and anyone else that you want to ask to observe as a neutral party. If you are going to be rolling clusters like crazy, you better have several pairs of dice of various designs. Hell, even if you have a lot of them I could just say "roll the dice and write them down and we'll get back to you in a minute". While you could try to fudge the dice rolls someone else is going to be watching out of interest which helps to check anyone that is trying to cheat. Their responses, verbal or body language will give me a means of observing your dice results to some degree. Things are just a lot easier if people can see it.
Playing MM is to agree upon using it's RNG, but it also locks individuals out by doing the dice roll one time. It would be a lot harder to cheat that way then with an RNG on a phone or tablet at a table, especially in a noisy game store where one could turn the sound down.
