Those 250 units were sourced within the last 5 months and from more than one distributor too. What that datapoint shows is that in the sample size of 250 units sourced during the last 5 months the observed defect rate was close to 1%. It does not say anything about the millions produced in the years past.
The quality is observed to be lousy today and bringing the quality issue to light may help change the future, but will not change the past.
Have you contacted Raspberry Pi Trading ?
They are more likely to respond via email than on a public forum, because you are not the first to have mentioned quality.
