The cynicism in my response, was more from the prospective of having purchased and used many of these types of devices in the past and the wishing that others avoid making the same exact error.
While we can disagree whether my response was merited, Why is one more detailed response better than a lesser and, yes, glib, response? isn't there room for all points of view or writing style of responses?

They provide little to no information. So why post? If you have no insight on the technology, the inclusion of "opinions" buries the discussion.
To be truthfully honest, this carb grid and items you mentioned such as the vortex generator and HHO devices can work in a narrow window of applications where the engine is far from optimized. There is nothing magical about it.
Vortex generators do work on older engines with "lazy" combustion chambers such as the old Hemi engines. A reduction in emissions and a slight increase in torque output at partial loads is the result, but along with this comes lost peak power as the vortex generator becomes an impediment at higher air flows. Modern engines already have tumble and swirl designed into intake and port configurations and will not benefit from these vortex devices.
HHO generators is a sticky subject on these forums due to the lack of understanding of a branch of industrial chemistry. On other scientifically moderated forums, many have concluded it is a plausible pathway to improved combustion via the seeding effect of precursor radicals if a very narrow set of conditions exist. However, the gains will only be in the few percent range in a stoichiometric mix.
Carburetors, by their very nature, have had numerous devices and circuits hung on them over the years to coax more power and efficiency out of what is essentially a very difficult proposition - fueling an engine over a broad band of loading conditions. I have on my workbench an old Carter ThermoQuad with electronic feedback and an old Holley Spread Bore with a custom air bleed plate underneath the primaries so that the carb could be used with an oxygen sensor feedback. Both carburetors approach the pinnacle of carburetor design and though I am sure fellows like OldMech can rebuild them in their sleep, I would rather have a few injectors and a handful of sensors and wire to deal with as found in modern engines. Earlier carburetor applications had "holes" in their operation that a carb grid could help. But, other devices could help just as well if not better. Holley had a set of high shear nozzles that increased fuel atomization as well as the availability of aftermarket sleeves that increased the vacuum signal across the nozzles with a slight loss in top end air flow.
All the above Isaac probably already knows, but someone looking for information can glean keywords and concepts to continue their investigation if they so desired. Saying " this stuff is all bunk", does little to help anyone.
