This was easily demonstrable, and lead to Jobs' infamous "You're holding it wrong" deflection.
To say that nothing was wrong and Apple was just managing PR from those pesky other companies badmouthing it is... the RDF in effect.
The only reality distortion field in effect here is the one that causes everybody to intentionally ignore the fact that every other smartphone had the same problem, and refuse to even acknowledge that fact when other people point it out.
It was a PR program.
Edit to add: I had a 4 sans bumper for 2 years and it worked great.
