Personally I don't impute any malice whatsoever -- these are soulless corporate entities -- but a for-profit company with fiduciary duty to shareholders releasing expensive, in-house-developed intellectual property for free certainly deserves some scrutiny.

I tend to believe this is a "commoditize your complement" strategy on Meta's part, myself. No idea what Deepseek's motivation is, but it wouldn't surprise me if it was a similar strategy.

In its ideal form, the sum of every participant commoditising their complements is how competition should benefit everyone — albeit at the expense of excess returns

Companies basically don't have fiduciary duties to shareholders. Also, Zuck has all the votes and can do whatever he wants.
