It's not "being cheeky". They know that the holy grail for AI is AGI. They know that people are going to see the acronym AGI and assume Artificial General Intelligence. They know that people aren't going to read the full article.

This isn't just a crass joke or a pun, it's outright deception. I'm not a lawyer, maybe it wouldn't hold up in court, but you cannot convince me that they aren't doing this on purpose.

of course they did it on purpose but thats not illegal. They are not at fault for individuals not reading what the acronym stands for and the intent that they place within the press release, which is very, very clear. They are not obligated or liable for others lack of due diligence.
