It's very likely if this passes people who used to be tech illiterate will start using pre encryption, such as the darknet's favorite PGP, before sending anything over, as all channels that are compliant will become insecure channels.
Much like it happened with vpns, chat encryption and ad blocking, people will be quick to catch on with a simple youtube video. Then we'll have sold our privacy for pretty much nothing.
I wonder how long it will take for these very technologically inept politicians to realise you can't legislate the internet to protect children, nor it is their job. Parents are the ones who are responsible for monitoring their children's internet usage. Make child monitoring software more accessible to parents.
I'm glad to see those taxes being put into pointless endeavours while our world is festering with inequality, recessions and climate annihilation. Pretty sure soon enough children won't need protection, because there won't be any children left as no one can afford them in order to sustain our billionaire population.
