This is a help article: https://monzo.com/blog/2018/06/07/is-monzo-a-bank/
It doesn’t add anything new, it just explains things we already know in a 101 style.
This is an announcement: https://monzo.com/blog/2018/04/12/transaction-tags/
It clearly announces a new product feature.
This is an announcement: ATM Fees Abroad: Landing Today
It transparently announces changes to the fee structure of the account for ATM withdrawals abroad.
Unless I am missing this being previously announced elsewhere, this post appears to me to be an announcement masquerading as a help post. The change is not documented in the title, or summary. Indeed, it’s only mentioned in passing towards the end of the article as if it has always been the case.
Does it make sense why I see it as different?
It’s a small change and won’t impact me, but it’s not as transparent as it should have been IMO. Also, is it just a coincidence that it’s late on a Friday? (I’ll remove my tin foil hat now 
)
