Quoted from PPS: I think that people making up things and having many theories without any basis is interesting reading, but can push us in the same direction as other suppliers which is to stay quiet or operate on our own forum which is not something I want to do as I think pinside is probably the best place to interact
I don't think people are making things up (as a general statement). As for theories without basis, that's pretty much a result of your decision to stay quiet when you are (apparently) bothered by a question/topic.
You already "stay quiet" by ignoring reasonable questions/concerns. You can't "interact" if you only do so on the easy stuff.
mof said it perfectly in the thread I started about PPS communications:
https://pinside.com/pinball/forum/topic/pps-mmr-communication-its-not-about-the-missing-coin-mechs/page/14#postbox
"The bottom line is — running a small business is about setting customer expectations and meeting them, and it's about maintaining trust with your customer base. When you fail to meet expectations, how you respond to the situation defines you as a businessman. It's not about being perfect. When expectations aren't met, if communication and action are delayed or missing, trust is appropriately brought into question.
We've observed vendors on Pinside (including PPS) deal with bumps in the road and overcome them with prompt communication and action. From what I've observed, many people were hoping for a high level of communication and responsibility regarding this issue to match the faith they demonstrated to PPS in a 3-hour sellout of the product offered. The customer base demonstrated a truly remarkable level of faith and trust up front in being delivered an excellent product. I presume PPS earned that trust with their previous track record with the customer base. I imagine that anything less than an excellent performance on the delivery side will meet quick scrutiny."
(And, AFAIK, no one, myself included, got an answer to why, if not shipping mechs with MMR is only an issue for a small fraction of orders, why not just ship them to those it is an issue for?).
