I conjecture that you wouldn't call someone a liar without some pretty solid data or at least direct observation.
Are you maybe saying that you've had 15 honorary degrees in various schools around the world, and the other people up their with you those days, or yourself, were utterly unworthy, to negate his stated observation?
Or maybe you're saying that what he said just doesn't mean much since all he claimed was that he respected the other recipients accomplishments. Sure I get that. One thing everyone knows about RMS, he's easy to impress.
some humans are scammers, most scams are repeatable. so if scammers in country X benefit from credential scamming, then it follows that their exist scammers in countries Y and Z that are also benefiting via their own application of the scamming technique.
Why? I conjecture the USA isn’t unique as far as people scamming credentials.
