I want to do more than just like stuff on facebook... hopefully this will present something more tangible. I signed up for the "Add a banner to your site" list. I can tell ~15k visitors about this over the next month at least.
As long as people are willing to pretend that the problem is only the US and not the entire West colluding then the easier it is for these governments to continue.
And GCHQ has less significantly legal restrictions than most other SIGINT agencies.
This may be true to some extent. But let me provide an anti-thesis to the statement.
For nearly a century (or more) everyone has looked at the US to lead in reforms and at times reversing reforms. What happens in the US is often used as a model by world governments as a blueprint.
If the US citizens, corporations and the tech community in general could get the US to positively change the distopian outlook/direction we (the world) seems to be heading in, this change would trickle down to the other countries beginning with the Western countries that you aptly state are colluding together.
In what respects? I can think of far more cases over the last century of the US lagging behind in reforms than taking the lead. In European politics, the US is more often channelled as the big regressive bogeyman (e.g. "we don't want US conditions, do we?") than somewhere to look to for reforms.
To the extent governments looks to the US, it is more often out of necessity due to the balance of power.
It's be fantastic if that changed and the US became a beacon of progress, but that will still take a lot.
In terms of surveillance, though, just getting the US pressure lifted would make local progress vastly easier.
More relevant today than when it aired almost a decade ago...
