It's unlikely that the Kazakh government would be able to do that much with it.
Kazakhstan has a population of about 18M and internet penetration of about 35% if they would really want to sift through all that traffic they are more than welcome to do so, just keep in mind that even the US would probably not be able to do so with any degree of effectiveness.
The only thing that Google et al. could do is refuse to provide service to Kazakhstan which would only harm the people even more, if you are a dissident you are already taking a huge risk denying people the ability to access information and to connect with others won't help to reduce that risk just only make it worse as it would only isolate them further.
China is doing the same, so do many Gulf nations to some extent or another, no one is arguing that we should not cooperate with China, cooperation is the only real way to effect change in those nations in the first place, or would you think China would be as open as it is today if we would have a technical and cultural embargo over it?
Western companies sell them hardware and software to process the traffic that they Capture. Cisco, et.al is complicit in this work, including the firewall itself.
