Is 'debanking' a problem?

Nigel Farage is inarguably one of the most influential and recognisable political figures in modern British history, and so his announcement that he has been 'debanked', with his provider of over 40 years closing his account, has triggered a conversation over how much power banks and other corporations have in British politics. Full respect to Anne, who hadn't heard about the story prior to our discussion, but who got stuck in anyway!
'Former UKIP and Brexit party leader Nigel Farage has reported that he has been de-banked, having the personal bank account he has used since 1980 closed without any explanation given. How do you feel about the bank's decision in this case?'
