Have you actually tried LibreOffice in a while? The Ribbon UI hasn’t been experimental since LibreOffice 6.2, which was released in February 2019. It is a normal option, called Tabbed, in the User Interface settings under View > User Interface.
Some have already suggested jailbreaking and installing Kodi but honestly, it’s almost not worth it if you don’t have a specific use case for it. The latest Kodi you can install is 14 vs. the current 21 which is super old. At this point I’d honestly then just go for some other media center solution (Raspberry, Mini PC, …). You could maybe use it as an AirPlay point to cast your MacBook screen but not sure how feasible this is in your case and I’d still argue there are probably better solutions
The date seems to be misleading. When you open the comments section and load all comments, you’ll see that there are quite a few comments that are 9 years old. The article is thus far older than what it’s saying, and it unfortunately showcases again how many people rely on very old (and in this case misleading) information about LibreOffice.
