I'm sure Siglent is very thankful of your ongoing interest in their products, albeit in a negative way. 
Why should Siglent be thankful in a negative way? That doesn't make any sense.

Positive contribution from an experienced technician like yourself would be highly respected especially if linked and compared to compeditors features and more so, features that are highly desirable.
What, again?

I guess you then missed the part where I mentioned for example that Rigol manages to display the major parameters of both channels of their DG1000z on a small display while on the new SDG2000X you can only see one, despite the larger display. The Rigol UI is also somewhat customizable, which the SDG2000X isn't (according to their manual).
You apparently also missed the part where Steve from Siglent America confirmed that the SDG2000X comes with the same poor selection of built-in waveforms as earlier Siglent AWGs, compared to as mentioned the Rigol comes with 3 times as much.
Considering that you missed that I'm of course no longer surprised that you also missed my point about EasyWave, which is a really poor and fugly piece of software. There are examples out there how to do a waveform editor properly (i.e. the free Tektronix ArbExpress) and which Siglent could have used as a template for coming up with something better, but no, they decided that even their nice new 1GSa/s AWG doesn't deserve better than this abomination of software. Which is silly, really, as the point of an AWG is to be able to create arbitrary (non-standard) signals, but if the toolset is crap then this somewhat defeats the point and makes the whole package a lot less attractive. Siglent doesn't seem to understand that.
We all know that you've some horses in the race but you should really pay a bit more attention to what has been said.

Siglent's representation here is high profile and therefore suffers some "tall poppy" syndrome but we must endure this, however all feedback is valuable, more so if positive if that is at all possible of Siglent products from you. 
Since as shown above your attention is somewhat lacking it's no surprise that you also missed that I complimented Siglent many times for their hardware, not just in this thread but also in other ones. But just producing good hardware doesn't cut it.
We all should remind ourselves, without the Asian TE products we'd all be paying many times more for our TE
Probably. But being cheap is only good enough as long as your products still do what they're supposed to do. Don't forget that a large part for the big brand price premium is paying for service and support, something neither Siglent nor Rigol can provide on a similar level. Also, some of the money paid for the big brands will be recouped when selling the kit after many years of use, while your cheap SE Asian devices will be pretty much worthless. Plus, some of the specs of the cheap kit are inferior. All that is what the low price is supposed to offset.
But being a SE Asian TE manufacturer is hardly an excuse for throwing buggy products onto the market and then leaving customers hanging.
and unless we contribute, quality would be slow to improve.
Are you joking? How much more can people "contribute" than reporting problems, especially when Siglent keeps stumm about when they will be fixed and what the progress is.
Plus, Siglent's "high profile" (whatever that is) representation in this forum could easily have been used to look at older threads, which would have shown them what has been criticized, and address that. The fact that the new SDG2000X suffers from the same UI deficiencies as other Siglent kit, comes with the same crap EasyWave program and that the new SDS2000X/SDG2000X aren't even available 'til December clearly shows that they missed that chance to improve.
How much more contribution do you expect paying customers to provide?
Now Siglent has strong English language support from North America's input to head office in Shenzhen much will improve in the foreseeable future.
Maybe, maybe not. So far my impression is that it's more of a one-way street, i.e. information flows from China to the US but not much back (or the back-flow is pretty much dismissed by Shenzhen, which wouldn't be at all surprising).
However, this product release very much looks like business as usual.
