No one's preventing anyone from building a better solution and making it available to consumers. Not a monopoly
It would be great if they could be altruistic to let anyone use them, but altruism isn't really a good path to profits in our society
Not to say they shouldn't be cheaper, but they'll definitely get there. We're pretty close to price-parity as is (just not tons of options).
This is as of 2018, and one would expect that the grid will continue to get cleaner as time goes on, which means the BEV options will get cleaner as well.
Most "atomic resolution" EM images you see are actually images of columns of atoms, since the imaging mode is transmission, so necessarily the image is summed through the plane of the sample (so atomic resolution is only in the perpendicular plane).
The techniques used in this paper get around the dose issue by taking many images of very many presumably identical proteins (called dose fractionation) at very low dose. Computer algorithms are then used to stitch together a 3D model based on the low-dose individual images. Making it really cold also helps things from breaking down under the beam.
