No Hoper, I think you are distorting the truth a little.
To summarise:
Cylinder damage/cracking is caused by manufacturer or the LAME/A&P.
Most likely they are of manufacture or from excessive heating issues and often unlogged as nobody would know. I doubt very much the LAME is the cause, who said they were anyway? Or are you fishing for a debate? 
Anecdotal stories from some posters is data/acceptable evidence
Anecdotal only to those who have not seen the data. Remember some on here have access to far more data and knowledge than the rest put together. For them it is not anecdotal at all.
CMI and Lycoming are conspiring with FAA/CASA to shut down a PMA organization
That is plausible, but who will ever know?
