I encountered something like this at work. It wasn’t pass related, it was just a means of getting people to make text responses. Ampersands were replaced with some gibberish format, which annoyed everyone.
I got some kind of explanation from our tech people, which I understood to mean that ampersand was used to indicate that what followed was live code. Turning the ampersand into gibberish text was a safety measure to stop mischief.
I’ve noticed ampersand replacements in some news feeds too
Yamaha makes lots of other musical instruments too.
The thing that puzzles me is that the Yamaha logo, 3 tuning forks, makes sense for instruments that you tune. But I’ve only seen it on their motorbikes.
