Someone, I don't know who, figured out the cause of the failures in
these Ford Explorer radios and posted the repair info online, I don't
know where.

Mr. "Shareamemory_but_don't_share_someone_else's_free_information" found
that information.
He said so himself, in a post to this group years ago.

Mr. Shareamemory began also sharing that other person's knowledge freely
on his own web site... begging for donations in the beginning.

Then he pulled his free page, and began his paypal business of charging
money for the info.

A few people from this group, already knowing what the radio fix was,
continued talking about and freely sharing the info themselves, which
cut into Mr. Shareamemory's new business.

Mr. Shareamemory began having his pictures of the problematic circuit
board removed from free hosting sites whenever someone posted them for
others to see, had his own free page removed from The Wayback Machine
internet archives so nobody could find it any more, and even
impersonated an attorney and sent bullying email threats to somebody who
posted their own story and pics of their own radio repair job on their
own web page.

In short, he stole someone else's work and made it his own, and works
diligently to prevent anybody from benefiting from it without paying him.

BTW, I have Mr. Shareamemory's old *free* fixit page, complete with
photos, still saved on my hard drive. I consider it still free, in the
public domain, just as it was when he posted it. I'd share it freely if
I knew how and where I could do it, without getting harassed and
threatened by the chump.
