I wasn't aware of this and very much take your point. I would not though expect to read in a Press Release from anyone:
"So, this sucks," "We thought we had a thing," "we’re bummed about this."
This makes me concerned as to their professionalism. While I appreciate this is very probably young people addressing an audience much younger than me, I'm 65, I don't find these appropriate phrases for a PR. Second language or not professionals should know this. One should always be very careful with public announcements and sensitive to the potentially wide range of people who read them.
