This kind of nonsense is typical of manufacturers of all kinds.
A proven problem / weakness is identified - in this case a latch that can be put in a position where it appears to be closed and is not. Their solution is not to redesign the latch so that it is unambiguous, their "solution" is to tell people about their crap design so they can say "we warned you it was crap so if you make a mistake it's your fault".
How's that for a Safety Culture we can all be proud of eh?
