Why do Microsoft Stream use .webm?

I dont understand why Microsoft choose to save videos made in Microsoft Stream as .webm-format. The format is not supported by the video editor app inside Windows 10, and not in Sway either? Why dont you just use .mp4? Much better compatibility.

microsoft stream
office 365

    I don't know who's decision it was, but it was a really dumb one. As an admin, I'm now getting complaints that they can't even embed webm videos into PowerPoint (web) or other Microsoft apps. Was there no proper testing or thought applied for this implementation? It's extremely frustrating since most of our users are on Windows 10 and do not have access to ClipChamp, nor the web version because it's not under our BAA at the moment.

      It's easy, MP4 is patented and require licensing, While webm is open source AND royality free. Webm also has alot better Compression ratio, which is kinda of important in the web.


      As for embedding streams into powerpoint, just do
      Insert tab > video video > online
