Sorry. I didn't mean that mean-spiritedly, even if I ended up sounding glib anyway.
People all have different motivations for getting into DIY. For some it's to have a given thing at a lower price than the manufactured version, or because they want a slightly tweaked version. Some simply want to see what it's like to put something together. Not a whole lot of people are into designing equipment end-to-end from scratch, because that is hard -- most are content to work from cookbooks and kits, and modify the design if they feel motivated to.
Many of them do cop attitudes regarding commercial products. In some cases the disdain is justified (mass-market receivers do mostly suck; some boutique audio is crap in a nice box), but in many cases it's the self-riteousness many people feel when they work towards exactly what they want rather than accept what's available. Sometimes it gets annoying. It's usually the veteran DIYers who've developed an appreciation for the designs of mass-market goods. These days, since all mass-market and most mid-fi electronics are largely chips on PCBs, DIYers have looked to 1970s and 1950s designs as starting points.
