Yes but they've done this before in countries like US. They went after the T Shirt producers printing the DeCSS on them and recently the whole tornado cash fiasco where they tried to make smart contracts illegal (although this was overturned).

Granted though I think DeCSS contained proprietary code so its a little different but unfortunately I view most governmental control and censorship to be braindead but I still fear they will do it.

They would have exemptions for corporate VPNs and encryption and for members of parliament and all that of course, but I could absolutely see them trying to fuck us all sooner rather than later.

I hope I'm just paranoid.
