Wire wrote that article in summer last year to prevent the German IT-Planning Council from adopting Matrix as the communications layer for its consolidated interfederal government-to-citizen messaging infrastructure in the public administration.
So be aware that, to my knowledge, this article is not a good-faith tech blog post but part of public affairs campaign / lobbying attempt.
Would be neat to have meta data encrypted in Matrix, but it’s not a deal breaker for most use cases imo.
Agreed, but metadata not being encrypted remains a fact. Sure, metadata of a single message might not mean much, but when combined with metadata of many messages from many users you can find out a lot about a person and their habits. Especially when cross-referencing with other data sources (social media of other users, phone location, etc.).

Absolutely, it’s definitely one of the major areas work on the Matrix standard is needed.
There is an MSC (= a spec change proposal) from September 2025 where the folks at Element proposed a solution for how to do this going forward: https://github.com/matrix-org/matrix-spec-proposals/pull/3414?ref=element.io
