You can always just undervolt the cpu and take out the gpu. Sure, a 1000w power supply is going to be inefficient at 20% draw, but if you already have old hardware it isn't always cost effective to replace it just because of a higher power draw.
Also the pi is great for stuff like dns and network storage, but it's going to struggle with transcoding as a media server. I can't speak for the 5 from personal experience, but the 4 was completely incapable as a jellyfin/plex server. I just use an old stripped down computer for media and the pi is relegated to dns adblocking.
How does the title victimize Google?... It literally just summarizes the article, and then in the first sentence of the actual article they flat out call Google an illegal monopoly.
