You have had success getting non-technically oriented friends and family to use a Keepass across multiple devices? Then you're doing far better than me.

I don't think your experience is representative. As I stated in my previous comment, I think the relative success of cloud-enabled password managers vs. more secure options like Keepass are a non-anecdotal form of support for this opinion. But I would be way off (which I also acknowledge).

Could be that those companies use marketing? Keepass doesn't market. Hard to say without any facts. :D
