What Intel meant at the time was "someone is selling our chips relabeled to a higher SKU and pocketing our cut". This happened in 1996 with criminal gang remarking 120 to 150, 133 to 166, etc, pocketing extra ~$30-50 per CPU.
Intel was so pissed someone else was making money on binning they locked multiplier on later 133/166/200, all Pentium MMX and later models ending easy overclocking.
Except the classic case of the Celeron 300a which let you go from 300Mhz to 450Mhz with a simple change of a motherboard FSB clock setting.
I was nervous when I ordered the parts - but stunned that it was so easy for me to do, and left me with a machine that was effectively faster than anything Intel was officially selling at the time.
FSB (and later BCLK) overclocking is what we got left with for a while until Intel killed that too with Sandy Bridge just after introducing special upscale K series CPUs generation earlier with Nehalem. All in an effort to sell gimped parts while charging extra for the whole deal.
