Which, to be fair, isn't technically dead. Apache OpenOffice, the rotting corpse of OpenOffice.org now maintained by Apache, released 4.1.16 just a few months ago.
What should have happened was that ten years ago Apache should have "retired" OpenOffice. That's Apache's terminology for projects which are abandoned. But instead it has limped on for all these years, sucking up valuable effort by users with Apache claiming that it'll be fine somehow.
Germany here, never heard of any issues regarding underground power (or phone) lines. Ultra High voltage (distribution network) is above ground here, but no issued with that either.
I remember my Star LC-10 had multiple fonts with different widths. There was regular, condensed, wide and NLQ (Near Letter Quality). The latter looked like it had been written on a typewriter.
I had a Star SG-10, labeled as "Epson Compatible". (Mostly)
The Near Letter Quality was essentially double struck by making a second pass at a slight offset, with the corresponding increase in noise and print times.
There wasn't support for the printer in AppleWorks, so my first useful program was a BASIC thing that you could set the font in the printer and then reboot into AppleWorks to use either the 10 cpi, 12, 17(condensed) or the NLQ setting.
Star Micronics Gemini-10X to Xetec Super Graphix interface card to C64. The bane of my existence seemed to get the sprockets synced and eventually started wrinkling the paper after a few pages.
Yes, it uses QEMU under the hood for VMs and runs LXC containers. But also, since recently, you can run docker images in it. Very handy, especially since it has 1st class remote support, meaning you can install only the incus client and when doing `incus launch` or whatever, it will transparently start the container/vm on your remote host
Edit: Further, the ooxml format was heavily criticised ~20 years ago, back when it was introduced. This is old news.
