This kind of plays into my theory that golden age of e-commerce is dead.
I wouldn't go that far, even if you had appended your sentence with the B2B word there. Not only Keysight is a drop in the ocean (#1305 in Forbes 2000) but, looking at the record profits seen by the e-commerce industry in the past two years, it is growing stronger than ever (one of the largest wealth transfers in history, some say). What I agree is that the golden era of direct manufacturing selling/supporting hobbyists might be coming to an end, but IIRC this was only running for the past 10~12 years window.
The internet opened up a lot of industrial stuff to the public, and now they're all probably remembering why they didn't do that historically. If you ignore how it pisses off some people who do put in big orders, as shown in this thread, i.e. typical corporate shortsightedness, it's probably not terribly profitable to deal with the public between the volume and privileges granted to consumers under law that a certain percentage are sure to abuse.
I agree with that - historically the dealers/traders were responsible for all this hassle and this direct sales model from the manufacturer might dry up. If anything, we can keep buying products from Keysight but via Farnell, Mouser, Digikey, etc., and they would keep handling warranties, RMAs, RMRs, etc.
Going forward a cheap LLC is probably the best solution, small customers aren't going to convince giant corporations to do anything, so you have to play by their asinine rules.
That is indeed the sound strategy, although the rules vary greatly from country to country - in US is not terribly hard, but in Brasil it can become quite cumbersome...
