"For Evernote's consumer product, the current encryption algorithms are chosen more for exportability under the Commerce Department rather than strength, since our software permits the encryption of arbitrary user data with no escrow."

International regulations are pretty insane. For example, France requires you to submit your software to them for review that's supposed to take up to 2 weeks. This isn't just for product releases, it includes everything, including patches.
Apple, MS and Google can get away with it because they have large legal teams that help them with all the various rules and regulations. For smaller companies, it's simply too massive to bother taking more than an off-the-shelf solution.
