I don't know what you're asking. They do it for the same reason Apple or Google or whoever steals all your data and hoards it. Because knowledge is power and on the internet data has become synonymous with knowledge so they think they're gaining an upper hand. Think about it, Facebook had a facial recognition thing like 10 whole fucking years ago that would scan your photos and guess who was in your pictures. The US government definitely has more sophisticated tools than that and all the storage space they'd need. LLMs have just given them the ability to process all that data they've collected on everyone.
