John, I completely agree with the statement that that conclusion is paranoid and suggest that you seek professional help (as you have suggested for others).  What Brent wrote was: "Kirk thought it was a risk worth taking but did not foresee two additional events."  How do you see a conspiracy theory in that?  How do you stretch that statement into a "well organized and financed plot?"  People make business decisions all the time and unforeseen events, from unexpected competition to vendor non-performance to a change in market conditions thwart those plans.  It could be debated if that constitutes bad luck or bad judgment, but if you are truly seeing conspiracy theories in that, you need help.

As one who advises public companies in order to pay the fuel
bills, I can assure those who are worried about Gramin's ultimate future
that it is highly unlikely that its stockholders will force management
to resign as a result of its foray into experimental avionics.  The cost
of the effort, whether successful or not, is unlikely to be even a blip
on Garmin's P&L.
  

When a public company become a "hot stock" like Garmin has of late, it looses a lot of its ability to do things that are right for the business and becomes a slave to the opinions of analysts that know little about the business and even less about the company's actual operations.  If aviation is perceived as a drag or an undue liability by the analyst community, regardless of whether that drag is real or imagined, it will become a very real and heavy boat anchor on the company's stock price.  In the short term, the stock market has a little to do with finances and business and a lot to do with psychology.  The bottom line and $$$$ on the balance sheet always win out in the long run but this week's and next month's stock prices are set by emotion, not sound financial reason.

The 42X was tested better than most experimental products.
Notwithstanding that testing, it turned out that the product had some
glitches in some installations (but not all -- mine never had the
problem.)

A good product works in all installations all the time.  Something that works most of the time in most installations may be good enough for a car stereo, it is not acceptable for something whose failure can cost you your life.

When the matter came to their attention, Crossbow addressed
it seriously, identified and fixed the problem and stood behind its
products by providing free upgrades.

Not only did they do that, they did that over and over and over again.  If you talk to the people actually doing the testing they would tell you that they would get a "we have definitely identified and fixed the problem" product that would fail in the same manner even while taxiing for takeoff.  So yes, crossbow "fixed" the problem many many times, it just never got fixed.

This is a sad situation for a lot of people.  

I agree completely.  There are no winners in this sad situation.

It is not made better by
making up fairy tails about the wicked witch of the west and the
grintch.
  

So please don't make up those stories and as you had suggested earlier, seek professional help if you can not help yourself.

Hamid
