I haven't looked sufficiently into it - on a quick read it seemed like a positive public standing against censorship. I have noted a number of left-leaning figures in the list and even more centrist ones, not necessarily from the UK though.
The majority would likely be to the right of the centre, closer or further away.
I suppose that some degree of interpretation will come into it in absence of a clear definition and self-expression of political adherence. Some of those could be catalogued as nothing more than Hollywood progressive liberalist, some radical civil-libertarians etc.
Left-leaning: Žižek, Stone, Varoufakis, Hedges, Sachs, Liu;
Centrists: Assange, Snowden, Robbins, Fang, Maté.
