Which is kind of weird, imo. Shouldn't increased competition spur increased investment? If your competitor's product is approaching or beating yours on some metric, isn't the answer to improve your product to differentiate it from the competition? To say that open weight models will stop the flow of capital seems to indicate one of two things: 1) the frontier labs have no idea how to compete, so they are giving up; or 2) they figure that investors will eventually shrug and say "eh, the open weight stuff is good enough, no need to do more research," and retreat from the industry altogether. In the former case, it makes sense to lobby for regulation because the alternative is failure. In the latter, it's an admission that their product has no differentiating qualities from any other in the category and the product is more like a commodity or a utility and not a machine to print infinite wealth.
