Security is a fallacy here because, being a US company, it is technically not secured by default as it has backdoors (or one has to assume it has backdoors and those cannot even be audited). Then it is just about the sense of security which is based on the threat model you consider threatening to you. You do not chose who you are the enemy of though and in fascist countries with no regards to the rule of law like the USA, this becomes a fairly important threat model to take into account.

Libreoffice is used quite a bit in administrations across EU. I would expect more stickiness to microsoft caused by legacy applications that requires windows to run rather than office.
