- Very few youtube videos
- No more "Scope Month"
- Daniel is hiding
and so on ....

Maybe they are concentrating more on the high end UXR scopes.

No I do not see anything wrong with Keysight. They just recently sent me an invite to their webinar "How to protect your satellite network". Very useful.  :-DD

And lower cost, though only after the NRE is revovered.

The other are still doing ASIC. R&S did it. Rigol did it.
It does allow absurdly powerful specs to flow down into lower market segments.

Rigol didn't, they have analog and ADC ASICs, but the waveform rendering is FPGA.

It does a bit more than that:

But in any case they invested in ASIC's which allows them to reverage the price advantage into lower market segments.

If I'm interpreting posts on this forum correctly, I think the Rigol DHO800/DHO900 actually do scaling of the display data to some extend when connected to an external monitor. I highly suspect Rigol is using a GPU to render the screens on these scopes instead of an FPGA. When using a GPU you get scaling (almost) for free.

I believe that just a standard android O/S scaling, it's not the actual waveform data in any way.

In that case I don't quite get what you are after. Do you mean you can get more information? Like more measurement positions? More horizontal divisions?
