To give some context, the reason why they are getting away with such brute methods is that the most people wouldn't understand the full implication. I would be surprised if this would prove difficult to enforce - the first thing an ordinary person would do when, say, Facebook wouldn't load is to call up the Kazakhtelecom's support and the support guy would tell them to "press that button that says 'I trust this certificate'" and they would comply. There also hasn't been an uproar re government snooping into private citizens' communication, the kind that US had with Snowden etc., so a lot of people are likely to accept the "for your own security" talk at face value without much skepticism. It's also unlikely that even heightened awareness will inspire much backlash, as there is no real track record of grassroots organizing, even when the government tightens the screws. To its credit, the government has been quite skillful at balancing at just below the limit of pissing people off enough to make them go to the streets for the last twenty years (soaring oil prices in the last decade helped as well).
