digital decoding is probably the best thing for usb scopes as they are flexible for reprogramming the fpga inside to do whatever you want, which is probably the reason for pushing open source. But 4 channels split between 1G/s with 350mhz BW (nyquist theorem?) is.... not great at all for $500

Yeah not good resolution. The reason for the split across channels thing is they all share a single DAC (according to their specs. Wouldn't it be an ADC?), so they are using time division multiplexing in multi channel mode.
Depends what you need it for. I get away with using a Logic Analyzer sometimes, when I just want to snoop protocol data in flight. Sometimes that resoution would be good enough, sometimes not.
