I think we have far bigger problems than Brendan Eich in the tech industry. Far more people have suffered or died in recent years from tax cuts and austerity lobbied by by some of the biggest billionaires (i.e. Zuckerberg, Gates, Ballmer, Musk, Bezos) than from the causes Eich has funded.
Can we truly call ourselves humanitarians when we continue to lap up everything that big tech gives to us?
At best, we're hypocrites for cancelling Eich whilst simultaneously sweeping issues like worker exploitation, political/medical disinformation, erosion of privacy, etc from the rest of big tech under the rug.
