They mention “measures restricting free and open access to the Internet”, which is a gross exaggeration.

The TLD .cat has “over 100 thousand active domain names”, but Spanish judges have decreed the shutdown of 10 very specific domains.

Nobody's restricting “free and open access to the Internet” in Catalonia or elsewhere in Spain; it is very confusing (or manipulative) to say so.

Web sites defending Catalan independence and organising people around that goal via democratic and lawful means are legan and stay open (and in fact, some of them receive generous public subsidies). It's only a few web sites calling for sedition and for disobeying the ruling of the Constitutional Court that are being shut down.
