It's kind of a shame, one of the thing I value most about working in tech is the apolitical stance a lot of companies take.
Typically, tech's stance is something like "socially conscious technolibertarianism". That's not inherently bad-- it's a philosophy with pros and cons like any other-- but it is a definite stance. You might be perceiving it as apolitical for one of two reasons:
1. because it aligns so closely with your view of how the world "should be" that it seems natural and obvious
2. because it doesn't map easily onto the usual Democrat/Republican camps of American politics, thus allowing it to avoid closely identifying with one of those parties and thus seem apolitical
So I don't think this is a shame - it's more that tech is now being more honest and open about what they were doing anyway.
It's impossible to be completely apolitical, but it is possible for a company to be involved in politics to a greater or lesser degree.
Yes. The jobs weren't their responsibility when the existed and shouldn't be when they're gone. We have other entities to worry about things like that, governments.
If we start dragging politics into it we will destroy things like open source that exist only because anyone can anonymously contribute without their race/religion/politics coming up.
But on other topics they should stay out of it.
