great - however you are one person, the large banks involved here have staff of a few hundred thousand each across several countries and with various backgrounds and norms, many who are also friends and have contact with each other outside of office hours.

I agree, one needs to keep work comms on approved software, I'm simply stating that while it's fun to be like "oohh big bad bank was hiding secret convos" it was more likely "janet i'm out today can you take the meeting with svp of <insert corp>"

Put another way context matters in terms of how the public should react to the news, not so much the result (fines) or the regulations / requirements.

Literally the only reason to use Signal is to talk about unionizing, drugs, or shady biz deals.

Texting your coworker, would the usual path, not some secondary software that requires both people to set up ahead of time.
