I had to read through your comment a few times to try to understand it. I think what you're saying is that ecological campaigning groups (particularly, I would guess, those such as XE without a formal hierarchy) are perceived by the current British government to be a threat to the establishment and so they want to prohibit these groups' use of encrypted group chats.

Personally, I don't think this is a particularly legitimate concern (and by extension, not one which I would assume the government has), since the whole point of revolutions is that they don't need to be planned; they are a groundswell of popular opinion turned violent. Even if encrypted group chats were necessary for ecological campaigning groups, I don't believe they are popular enough among the British public or violent enough to make even a minor dent in the Britain establishment.

And I question how much terror stopping traffic generates, generally more just irritation.

pretty sure “eco terrorism” includes things like sabotaging pipelines and such too.

though to your point, that form’s more of an economic weapon than it is terror.

And I that was kind of extinction rebellion's whole point: money talks, let's hit the money, and sure enough the gained attention. However, if economic crimes were equivalent to terrorism there'd be a lot more fraudsters in high security prisons.
