Note that it is not just Toshiba that is having some difficulties, and remember that the individual batteries may be the same across different mfg’s battery packs in the same way that something like a USB jack in many different products may come from a single generic manufacturer but affect many different end-companies.
That is not why Toshiba is on my Lifetime Boycott List.
Toshiba is on that list because they circumvented US export control laws to sell militarily restricted equipment to the Soviet Union, which the Soviets used to produce highly sophisticated propellers for their Akula Class Attack Submarines.
Toshiba knew exactly what they were doing, and they did it for the money. That is why they are on my Lifetime Boycott List and they should be on yours, too.
