There are several reasons why people might want to add a PowerPoint export option to their pitch presentations. Some possible reasons include:

Sharing the presentation with a wider audience: Adding a PowerPoint export option allows the presentation to be shared with people who were not able to attend the original pitch, or to be shared with potential investors or partners who may not have been present at the pitch.

Making the presentation more accessible: A PowerPoint export can make the presentation more accessible to people with disabilities, as it can be converted into a variety of formats, such as large print or audio.

Editing the presentation: A PowerPoint export allows the presenter to make changes or updates to the presentation after it has been delivered, which can be useful if the presentation needs to be revised or updated based on feedback from the audience.

Repurposing the presentation: A PowerPoint export can be useful if the presenter wants to reuse the content from the presentation in other contexts, such as in a blog post or a conference presentation.

Overall, adding a PowerPoint export option to a pitch presentation can be a useful way to share the content with a wider audience and to make the presentation more accessible and editable.
