many "mainstream" manufacturers make UL gear …. plenty of people use em …
BPL has even given quite a few positive reviews … UL down jackets, down sleeping bags, some mainstream packs brands, canister stoves, etc …
one can go UL if you want by buying stuff solely at a retailer like MEC …
many people buy "mainstream" because they can actually try stuff one, they can return it fairly easily, and the warranty from some of those retailers/manufactureres is no questions asked
you also have to ask yourself what is "cottage" … theres been at least one "cottage" manufacturer that manufactures in china … when a "mainstream" brand like westcome that is sold in REI makes everything in vancouver, canada

Oh sure, there will always be a small influx of brand new customers into this little ultralight niche that will keep the cottage industry in business just enough so they can write off their backpacking trips and make payments on their logo-emblazoned trade show campers, but their quest for pursuing innovation doesn't seem to reflect the availability and cheap costs of new manufacturing technologies, state of the art fabrics, and real design. Instead, the cottage industry reinforces that paradigm of gear that is "made in my garage with substandard equipment from sketches on paper scraps using an uncalibrated ruler and dull scissors."
There remains no question at all that the cottage industry is able to give us the lightest possible equipment so that we can make the most of our wilderness travels in the style that reflects our commitment to carrying the least amount of weight.
However, the gap in weight (and specifically, in the performance:weight ratio) between what cottage manufacturers offer and what larger manufacturers offer is narrowing. So, given the option between an "ultralight" piece of gear made by a cottage manufacturer and an "ultralight plus a few ounces" piece of gear made at a higher quality, performance, durability, and aesthetic standard by a manufacturer with a more recognizable brand name and wider (read: more accessible and convenient) distribution network, then the battle lines become quite a bit less defined.

IMO this paradigm has come true … its was never that manufacturers could NOT make light gear … but they didnt perceive a market demand for it
this is changing … witness the popular TNF verto series, or the slew of UL rain jackets, etc …
its simply a matter of consumer demand
