I'm completely pro-privacy, but I need to ask: why would ordinary people's ordinary data need better security? Even if iCloud might be decrypted by the government. If it's data like bills, government issued photos of ID cards, family photos, it will most likely won't matter at all and the security is good enough, just like anything available.
Once you do have a reason to encrypt something, learning GPG, LUKS, etc. is not that hard or that technical.
