Speaking as someone who doesn't use any of these things, at least half the problem is the people who push these pieces of software. Hint: telling someone "oh, your preferred software is crap, use this instead" when what they have is already sufficient for their purposes makes you look like a liar and turns people against your message because they don't like being insulted. There are examples in the comments here already.

There is a type of person who instantly jumps on new software because it is new . . . and y'know, that's fine. We need those people, or software will never improve. However, most people don't think that way and need to be offered a compelling reason to change. "This new software has this great new feature" may be a compelling reason . . . for someone who needs or can use that feature. "The codebase of the software you're using is old and crufty and not attracting many developers" is not a compelling reason as long as there's at least one person around providing needed patches. Even "the software you're currently using is completely unmaintained" may not be a compelling reason if the software continues to work and doesn't have any known major security issues.
