If I'm reading the post correctly (and I am no expert in the field), they're saying "this test will be obsolete by end of year, as better tests become available". It was an EULA, which is by intention "we wouldn't approve this so quickly except this is an emergency", so it's not surprising that as better tests were developed they would withdraw the EULA.

Given that they were withdrawing it with several months' advance notice, I doubt there was anything massively wrong with it.
