"A lot of developers are interested in getting access to ChatGPT plugins via the API but Sam said he didn’t think they’d be released any time soon. The usage of plugins, other than browsing, suggests that they don’t have PMF yet."
There might also be some concern related to the comments on the approach to plugins. Plugins not having a product market fit reflects slightly negatively, on the companies powering the plugin and OpenAI. It becomes harder to get companies to invest time in creating plugins. I am not sure if the there was an option to remove just the issue sections of the post.
