Another excuse, BA how lame!!

can someone explain?
.............................
On the hashboard there are no electrolytic capacitors. Everything is solid. They cannot explode with flame.
This 1500uF electrolytic capacitor ended on this board by mistake: We have added it while trying to debug the noise in the SPI and forgot to delete it from the BOM. By the time we got the backplanes they were already mounted. We did not think that it might be a problem and we were pushed by you (customer) to ship asap therefore we have not removed them. Removing them would have caused at least 1 day delay.
We also don't need the 470uF solid capacitors from the backplane.

That is ofcourse bullshit and they know it..
they have a huge problem on their hands cause the machine is CE certified. that means that if something happend house on fire, human electrocution and its caused by the BA miner they are responsible !!
Authorities would ask the TCD files of the miners. (Technicel Construction Dossier) if is not complete our the product did not pass certain test well you will loss your balls ....
it is absolutely bullshit.
so they had this cap that shouldn't have been on the BOM, but was.
and if they're not supposedly doing anything, why was there enough load on them to blow them and start a fire.
these guys are fucked. these caps are likely indicative of another problem. just putting bigger/different caps in the system doesn't solve the underlying issue of whatever caused these to fail.
are we supposed to believe that they over-rated every other part BUT the caps so we'll be fine as soon as they upgrade the caps?
BS. this is more likely a design flaw that goes well beyond the caps.
