They want private progress. They want to be the industry leader in whatever it is. They're not progressing humanity, they're making a great fiscal quarter.
Llama 2 is more "open" than Llama 1. Llama 1 was just leaked, and technically not supposed to be available to the public. Llama 2 is actually officially released, even though there are restrictions in the license.
As The Register noted earlier, the community agreement forbids the use of Llama 2 to train other language models; and if the technology is used in an app or service with more than 700 million monthly users, a special license is required from Meta. It's also not on the Open Source Initiative's list of open source licenses.
