You can be "socially liberal" and not be terribly progressive at all, and in fact that's what I usually see in the tech industry.

Eg. Support gay rights and environmental causes, but don't really give a shit about poor people.

That has been my experience as well

But "being very liberal" is not the same as "being very pro USA Democrats".

Liberals are often right wing parties in other countries. Basically you have a scale from socialism where everything in your life is dictated by social contracts to liberalism where almost nothing in your life is dictated by social contracts. The left in the US calling themselves liberals is kinda like the north korea calling themselves "democratic people's republicc". Their only liberal agenda is freedom from the Christian social contract.

Yet we are on a U.S. based website talking about a U.S. company and its American workforce and a story published in a U.S. newspaper, so we will stick with the common convention and not go on semantics tangents.
