It is not specific to farming. Handmade, artisan stuff sells well, even when it is objectively worse. And in general, people are more sympathetic to small businesses than big, faceless corporations. We value the human element I guess.
As for food, we tend to equate big farms with everything bad with current agriculture, even if it doesn't have to do with it: crops bred for yield instead of taste/nutrition, monoculture with pesticides/herbicides, ... It is partly true because small, traditional farms then to focus on quality and ethics/sustainability/... rather than price, because they can't compete on price.
With industrialized products you know they want it cheap, resulting in crap product that didn't need to be crap.
For example once I had to repair my Electrolux fridge, when I opened it up I saw two very nasty things: 1. the holes between parts were all misaligned, to the point it was impossible to insert the screws intended to go in them. 2. it was then glued with a ton of glue spread "randomly" all over the place, it was obviously shoddy.
And the issue I had to fix in that fridge? They used the cheapest "defrost" button they could, one that notoriously got stuck often, so your fridge would stay in "defrost" mode forever and stop working, the solution was disassemble it, force the button back with a screwdriver, assemble it again... every time you used the button.
I'm looking at these cabinets in the stock room and they're crap. No joinery, no screws, just flat pieces of cheap wood glued together. So I go to joke with the woman who works in that department about how cheaply they were constructed. She looked me dead in the eye and told me, oh no, these were the nicest cabinets we sold in the store. Top of the line. They even use extra glue to make them sturdier.
I know a guy who can't go through a drive through without lecturing everyone in the car about how being able to get 400kcal for a buck and a half is an amazing feat of societal progress. But he's old and emigrated from Poland so...
My example may be an outlier but there's plenty of people who are happy to get Chilean produce in January and don't care how much methane their 75/25 beef emitted. HN has the spare cash and brain cycles to care about a lot of things that normal people don't even think about.
Despite the size, the general methods between a smaller and a larger farm are not that different imho. But the amount of tech in a modern tractor was and still is amazing, and at the time the average car was definately not up to par. "automatic" GPS assisted driving, "laser" assisted driving (on harvesters). Beyond that, most of the "management" data was already digital 15 years ago, partly due to compliance requirements. And satellite imagery, soil samples, etc... were at least partly integrated.
And I would still call this a farm! Times change, and clinging to the old times in some nostalgia doesn't help. (I don't want to imply that you do!)
And on a slightly different perspective: I don't think bigger farms necessarily produce worse food, generate more externalities, etc... The processes are much more optimized, and at least I think the potential for better food with less externalities is with bigger farms. Also it is a somewhat bogus comparison: Mostly nobody complains that their car / laptop / smartphone comes from a factory, but for farming there is this strange preference for something of 50-100years past.
