Got to page 9, a fair amount of shit chatted from both sides, IMO.
Of course this cafe is gentrification. The reason it's been targetted instead of some nearby overpriced bar is that it has become symbolic of clichéd hipster wankerism, and lazy, price hiking capitalism. Someone comparing it to the markup in pubs. Not really a useful comparison, IMO. Compare it to the markup in a greasy spoon, if you don't want to be comparing apples with oranges. And then accept that the people who own it are chiseling shysters.
As for the protest itself, it is not right to say that anyone who doesn't agree with the methods class war used here is a liberal. That's such tedious "my politics are more hardline than yours, and thus better" bollocks its unbelievable. As I understand it, there were kids in the cafe, and definitely some pretty innocent adults. I'm willing to bet a fair proportion of the cafes customers are not remotely hipsterish. Normal people, who were pretty fucking terrified at the burning effigies, smokebombs, graffiti and masked men outside. Fucking shitting it, I imagine. How anyone can be remotely pleased about this is beyond me.
Of course the place is a valid target for protest, and I would never say that disorder should be off limits as a tactic to use. But this wasn't one of those times.
