If a significant amount of people “misunderstood” you, it’s not their fault, but yours for not clearly communicating or not tailoring your communication for the target audience.

Same here: if people play the game “wrong”, you didn’t design it properly and/or marketed it completely wrong.

Sure, there will always be “dumb” (or too clever) individuals who you simply can’t properly address and satisfy, but if the group is large enough to be loud, you failed your job.
