> Unions exist primarily to engage with employers, not government.
Labor parties in countries like the UK and Australia specifically exist to act as union-supported (and funded) parties. Unions do exist to help deal with members' employers, but they also exist to allow for collective political action.
An obvious example worldwide is teachers' unions (though you could argue because their employer is the state government, the union is fighting against their employer). Another example would be the strikes in the UK during Thatcher's time in office. Not to mention that basically all workers' rights legislation in most countries came out of battles between unions and governments, hence why they are so "weary" to "permit" unions to take political action -- because collective action works.
> So you'd need workers to unionize (which they have NOT done to deal with their employers) [...]
There's a saying about the second best time to plant a tree being today, and that applies here. This battle is most likely already lost, but actively choosing to not learn a lesson from it (unionise and mobilise for the next time this happens) is simply foolish. Ideally the technology industry would've unionised 30 years ago, but you'll never have any strength if the immediate response to someone saying "we should unionise" is "even if we unionised right now we couldn't solve $current_problem". Even if that is true, maybe having that infrastructure in place will allow you to solve tomorrow's problem?
> I think the real question here is why tech companies (or rather their CEOs, founders etc) are not making a fuss.
I hope by "fuss" you mean "shutting down operations until demands are met". Plenty of CEOs blogged about how insane the aforementioned anti-encryption legislation is (as they have in most of these cases). Looks like that doesn't work, maybe we should stop trying the same tactic?
> Politicians ignore us because 90% of people are not informed and choose not to think about history when these issues come up.
If (hypothetically) Google shut down for a week over this or any other bill, it would not be passed. They ignore us because all of our complaining is petulance -- it's not a substitute for action. That's the entire historic purpose of general strikes.
