IIRC, in their "research" they filled condoms with a fluid containing millions of microscopic balls the size of the virus. They delcared that condoms won't stop transmission of the virus when they found that after several hours some of the capsules had permeated the latex.
I guess they're right in a real-world sense if the guy ejaculates 1/2 cup of semen and the girl keeps the condom in her for a couple hours afterwards.
Are you sure it was "hours"? (how many hours?)

Regardless of whether this point is valid, condoms have a 20% failure rate in real world usage in preventing pregnancy.
A woman can only get pregnant 7 to 10 days per months, if the condom fails.
But she can get HIV 365 days a year.
So by simple math, the failure rate at preventing HIV transmission for condoms will be MUCH higher than 20%, as the article in this thread proves.
This shows that it could possibly happen, not what the odds are that it would happen.
This is similar to using research results of developing an amino acid chain from electrifying a simulated "primordial soup" to say that the chains could have formed without direction. It doesn't say they did or would or what the odds are, just that it is possible.
