We're talking here not about Amazon warehouse staff, but white collar software and systems engineers. These are people with many employment options.
I am totally free and valid to criticize those who go work for Amazon, the CIA's sysadmins, or those who go work for Microsoft, who makes the software that helps the USG run concentration camps, same as I am to criticize people who write software for smart munitions at Raytheon.
To play the race/orientation/gender card to shut down entirely legitimate moral criticism of certain employers is entirely unreasonable. :(
