I wasn't aware of this proposed preface[0]. It's a great read and is, interestingly, somewhat applicable to the TikTok situation. However, you are incorrect, the preface does not say the book is intended as an attack on the UK, European, or US governments. What it does discuss, is how, primarily, the British intelligentsia resisted the criticism of the USSR in the book because of the wartime alliance between the UK and the USSR. The preface makes it quite clear that Animal Farm is in fact an attack on the USSR specifically.
