I don't think it has anything to do with any conspiracy. All the commercial banks in the UK don't belong to one person or to one family, and they don't belong to people who can agree on something, knowing they will be losing profits because of that agreement. As it was nicely put in the end of the article: " Its just that the answer will be to work around them rather than with them." And I'm sure, since Bitcoin is perfectly legal in the UK, that there are banks there which won't lose the opportunity to replace those with bad attitude to BTC in the business.
