There are special interests groups on both sides of the issues but that then is a wash, they net out. The difference is that pro-gun, anti-encryption aligns nicely with business (concentrated power), against which you have the interests of average people who are harmed by these two things (distributed power). You tend to see concerted, continuous astro-turfing and the like for the former because their concentration makes them highly motivated. Whereas average people only speak up as aggressively when their awareness reaches a critical threshold, and that tends to go in fits and and starts, it depends on problem highlighting in the media. Businesses can afford to keep their PR departments working every day.
