Thank you. This article provides better context to the decision. The initial step aims at 40 people in one of the ministries by next year. It’s a start, but a far cry from the misleading main article in the post.

Not only Slack - it is likely also a replacement for Signal. Even if Signal isn’t a US entity, it is still hosted outside of the EU.
