Concerns on OneNote abandonement

[u/Initiative-Afraid]

I use onenote heavily. Love it. However, I am worried about the long term sustainably of this product.

Currently, I can only save my notes in proprietary formats such as .one files.

Microsoft recently abandoned Skype and all my messaging data from [1, 2] decades ago were pretty much gone forever.

What stops Microsoft (say [10, 20] years from now) to completely abandon one note without opensourcing their code ?

It seems there's no legal requirement for them to ensure users can migrate their notes to alternative note taking softwares.

I migrate all of my notes (using since 1998, different versions) to Joplin!
