aren't they majority funded by Google, MS, Amazon, NVIDIA, Sequoia, etc?

It's not like you can take $30B from these companies at a $200B valuation (the valuation is based on something) and then not be capitalistic.

Google owns 14%, Amazon 15-20%, founders 20-25%, VC ~30%. MS and NVIDIA ~5%.

They have a Kill Switch, but the reality is Anthropic is just one boardroom crisis away from becoming exactly like OpenAI

Google and Amazon don't have voting rights (because of competition laws), but they supply compute (survival rights)
