The second “wind” is as in “I wound up the toy car and, when I released it, it zoomed all the way to the other side of the room”. In this context, a “long-winded response” is one that metaphorically winded the coils that make the speaker go.

The more primary meaning is this one (copied from Oxford Dictionary of English): move in or take a twisting or spiral course. The etymology of the verb ‘wind’ (also from ODE) is: Old English windan ‘go rapidly’, ‘twine’, of Germanic origin; related to wander and wend. Long-winded = the speaker’s words/thoughts wander in circles for a long time.

Don’t spread this nonsense, please. All of Wikipedia’s content is already free, stays free and is still in the same place as ever. What has been sold to AI companies, that have already been scraping and using the site for years for free, is API access to WP’s material, suited to AI companies’ needs and hopefully less of a burden on WP’s normal infrastructure.

The deals mean that most major AI developers have now signed on to the foundation’s Wikimedia Enterprise program, a commercial subsidiary that sells high-speed API access to Wikipedia’s 65 million articles at higher speeds and volumes than the free public APIs provide. Wikipedia’s content remains freely available under a Creative Commons license, but the Enterprise program charges for faster, higher-volume access to the data.
