I have no experience with Seth, nor do I know the OP, but I think the post has value and the various responses confirm it. It also is a point lesson about documenting issues even in the absence of already prevailing and well known data and the plight of whistleblowers around the world.
Think of the various examples in life that are much bigger in scale where silence can be purchased and a festering problem be allowed to boil away with damage to others that could have been brought to light earlier. I'm not comparing the scale of this seat issue with bigger global problems but the situations are many similarities:
1) Catholic church scandal - for years priests were shuttled from parish to parish to cover up widespread abuse. And who knows how many hundreds of complaints were either not believed or silenced through other methods. Imagine someone accusing your priest of these things when your own experience is only positive?
2) Spider issues on 2nd Gen FJRs - complaints made on the board for years eventually leading to board members creating fixes. It was only once complaints were filed officially in Canada that a recall was finally issued. If everyone had suffered in silence, or if Yamaha had decided to silence complainers one by one (why didn't they do that? it would have saved them a lot of $$) then a recall would likely never been issued.
3) Mulitple cases of water contamination caused by fracking (many documentaries available - I recommend watching Gasland) - in several instances people who's water supply has been destroyed have been bought off by gas companies agreeing to provide them with truck delivered water in exchange for silence. Those agreements keep wide-spread solutions from ever being forced to the surface.
So what does the post and follow up show? Many of these same traits:
1) People accuse the OP of an agenda even in the face of some proof he has acted in good faith through the attached email chain - it is not consistent with their own experience so should be dis-believed.
2) People from both sides reporting anecdotal evidence to support opinions. But it is in the reporting of both sides that you actually can actually begin to see trends and statistics that are much more valuable than just single point data.
3) And finally - a response from the subject once the accusation goes public in a respected forum. This is the best outcome and one of the great reasons for the existence of forums like this. Is there any reason to think that without the public venting that it would have been resolved? There's no reason to think so based on the email chain and lack of progress prior to the exposure here.
In any case this thread seems quite interesting and valuable on many fronts. I agree with Tom - hopefully Mr. Laam sorts out his business and finds a way to successfully expand to meet the demand. He obviously does good work and it would be a shame to see it disintegrate - its great to have respected and trusted businesses out there with whom we can trust our money and our toys
