They pass the initial law as opt-in. That allows them to fund the initial infrastructure.

Then they make it out-out. The change doesn’t get much attention because the funding is already in place and “think of the children”.

Then they add political thought crimes to the filters.

Then they make it so you can’t opt-out.

This one is optional. Thousand of pages are blocked with court orders and hundreds of thousands are blocked categorically(porn, copyrights etc).

PayPal, Booking.com and many more are illegal due to data protection or business guild reasons.

Netflix, Prime Video, radios, podcasts etc are subjected to censorship by TV&Radio broadcasting regulator and are required to register for a license.

Social media with user base over certain number are required to be licensed.

The world mostly caught up but there’s still some way to go.

In this case they are opt-out, so there is a problem.

If they exist, we are one moralizing mad government away from opt-in to opt-out to no option.

I'm not aware of any such services in the Czech Republic, for example, opt-in or not.

I'm pretty sure Montenegro doesn't block anything on the internets.

It's a concern for me when they no longer become opt-in to prevent dangerous things like "misinformation" and "terrorism" and most importantly copyrighted material.
