As for Louis… honestly, I prefer his tempo. It feels more genuine, less like he’s putting on a show for the camera. In the tech world, take Craft Computing, LTT, or Jays2Cents as examples.

LibreOffice is the usual go-to for folks wanting an office suite, that respects privacy, and FOSS. It can read docx files, but it can mess up formatting. Still, for many it’s the preferred choice. It’s got the best reputation.
