I'm pretty sure about it. No one who suggested that deserves to be taken seriously. But intellectual property theft is a legitimate concern and comparing them as equal concerns is disingenuous.

Lots of people produce content and make a living off of 5e, and not just 3rd party producers, plenty of people use patreon as a means to distributetheir work. Will the ai be trained exclusively on WOTC playtesting or will it be able to scour the internet for plot hooks and npcs and loot and whatever else it needs? It's inevitable, and well known that some of that content has been reposted and copied in various places across the internet. The damages they suffer from user piracy wouldn't be comparable to an ai running multiple games on an online platform owned by the 'world's most popular rpg' not to mention that they would be charging for at least a onednd or dnd beyond or whatever they're calling it this week, subscription.

It's not as simple as "oh cool, more people could play". It's just their next attempt at eliminating the third party market.
