Regrettably this is so because there have been documented cases of fraud in
badge and record claims. Proof that there is scum in every pond I suppose.

Now whether the design of IGC logger security is efective at preventing that is
another question.

So, what changed is the technology, not the price
tag.

But the comparison ought to be between the cost of
a logger that's approved, and one that isn't. *To produce

it's cheap, but we aren't allowed to use it.

What seems to repeatedly get lost in the discussions is that the IGC
Approved logger STILL requires that you trust the OO. Once you've
made that conceptual leap, the case for COTS becomes clear. There
are simple and effective manual procedures which provide equivalent
security under a COTS scenario. So, statements that COTS somehow
inherently provides a lower level of security are just wrong. It IS
true that there are a few more manual procedures required, such as
sealing access to the data port, taking control of the recorder during
download and applying a little more scrutiny during flight analysis.
IF these procedures are followed, an equivalent level of security can
be achieved.

Why is the OO required for an IGC Approved logger? For example, I own
an LS8-18. I'm going to try for a record flight in Standard
Class. Who confirms that the glider was appropriately configured
for the flight claimed? The OO. Just one of dozens of
examples.
