My guess(!): Big topics are already crowded by big channels which get an algorithmic boost because of their past success. Its harder to get your slop prominently shown and establish your content slop farm with these topics. While with niche topics its easier to get your video to the top of the search results.
There are opensource tools like https://n8n.io/ to automate the creation of slop content. From what i heard its piss easy to setup. Like here is a half an hour tutorial to set you up:

Then you shit out the slop content and hope your channel picks up. If it fails to drive numbers you abandon it and start with the next channel with the next topic variation. If you get lucky and the algorithm blesses you, you continue to shit out hundreds of videos.
As seen eg in the video of redlyne about the dead internet theory. Where he looks a bit into the slop channels on youtube and other stuff:

It already rubbed me the wrong way how soon they sunsetted support for GCN cards. Especially since they introduced Vega 8(?) products in APUs till 2021 or something like that? Which means it should atleast still get support for another 2 years from here on now. Instead support ended years ago.
But at the time i could kinda see how they wanted to focus on RDNA. Still shitty but there was atleast some resemblence of a technical reason there. But now trying to stop support for RDNA because of the focus on RDNA is just fucking laughable.
