> How does this ruling affect the company's right to free speech in the US?
As I understand it, not at all.
I don't think the British institutions care at all about their rights to do whatever they want outside the UK; the problem is, 4chan does provide access to people in the UK, so it's a bit like a pirate radio station that the UK would like to not be receiving owing to the station's complete lack of interest in following UK laws.
To put it another way, if 4chan blocked the UK, the UK would consider this development to be appropriate. UK might not cancel the penalty fine, but that's because the offence for which it has been issued has already occurred; after all, nobody gets out of an already-issued littering ticket during a holiday by returning to their home country.

They really wouldn't, otherwise they would've done that already since it is well within their power to command ISPs to blackhole any offending website. That they chose to levy fines instead tells me all I need to know about their true intentions.
