What is this? Someone said something nice, and you need to "restore balance"
For example, as we speak, Zuck is lobbying congress to ban Tiktok. Putting aside whether you think it should be banned, this is clearly a cynical strategy with pure self interest in mind. He's trying to monopolize.
Whatever Zuck's strategy with open source is, it's just a strategy. Much like AMD is pursuing that strategy. They're corporations and they don't care about you or me.
Llama is usable by any company under 700M MAU.

EDIT: Looks like they did open up commercial use with version 2 with the explicit restriction to prevent any major competitor to Meta from using Llama, and that any improvements related to Llama can only apply to Llama. So an attempt to expand the scope of usage and adoption of their proprietary model without their main competitors being able to use it, which still fits my original point.
