The problem stems from obfuscation, SAC using the small print to move the goal posts, then when it is found that move was suspect, not telling operators (as far as we know) the whole story, & as time goes on & further problems arise people will draw their own conclusions.
I suggest you read MWs paragraph again
"You obviously missed the point I was making i.e. is this just an issue that is unworthy of serious attention, because at the progress rate to date and lack of clarity on the root cause for the MRGB cracking I would have to assume that SAC are not doing their product's reputation any good whatsoever. They may well be working diligently behind the scenes but I've been patiently waiting to see the outcome. Based on the latest future MRGB release dates and our immediate need for the upgraded MRGB I personally am extremely disappointed. We are over 2 years now from 491, coming up on 4 years since Broome, more than 9 years since SAC knew that the MRGB couldn't last more than 11 minutes."
