This is such a hugely superior approach to the traditional single signer petition or mailing campaign. I think to should be studied by citizens groups worldwide.
I'm one of the founders of Stop Killing Games. Me and a large group of other people have gotten annoyed at this cycle and have taken it upon ourselves to make such laws impossible to implement in the future. We're organizing the campaign now - this is fully separate from SKG, but a bunch of the same people who helped SKG succeed, and a plan that takes into accounts the learnings from SKG.
We're looking for people such as politicians, lawyers (EU/US/UK law), journalists, and donors who want to see Chat Control dead forever. If interested, email stopkillinggames+hn @ google's email service.
I think the value proposition for VCs and C-suite is pretty obvious here, you get to keep the government's hands off your communications and internal systems, which is directly where Chat Control is headed. Even avoiding the cost of Chat Control compliance (dev work, devops, legal, ...) can easily run into 7 figures for a larger corporation, and 8-9 figures for the top players.
Why would mass-emailing be effective, though? This one instance strikes me as the exception, not the rule, especially in a world where I see calls to write to your local government all the time (and basically none of it results in anything)
It costs them nothing to ignore emails. There's nothing on your end of the argument to use as leverage. It doesn't put any barriers to just right click->deleting the emails, or answering with something akin to "Thanks for your concern, but this isn't about you and we know better than you, so please stay out of it", just worded in a vaguer and more polite way.
The biggest difference is that there's little effort involved here. One click to send mass emails out to all relevant politicians. No they can not ignore a constant stream of emails from the electorate. Frankly, it doesn't seem like you understand why this site was different or effective.
