That's not entirely accurate. ARM Electronics physically builds it's Windows based DVRs in house. I won't vouch on who's software they use, but the actual construction of the units is something they over see.
While some of the things you are saying are absolutely true, the bottom line is that it isn't 1999 anymore. The market is different, the way equipment is bought and sold is different. An influx of overseas equipment has changed the way we as an industry are going to have to do business. Throwing a little fit isn't going to make guys like Sanyo, A/D and Pelco the only players again.
Do I think it's right that these companies post "pseudo" correct specs? Of course not. But that's not going to change the fact that there are a million Speco/Viteks/ARM/insert companies around and many are here to stay.
If you hate the industry so much, you should probably just go find another one.
