True, but what about distributing the installers? Man in the middle attacks are a potentially big problem for something like Maidsafe. You may not need ssl or tls, but that doesn't mean you shouldn't use it anyway.
Here are the two main reasons why I think you should be using HTTPS (thanks to the medium):
Protect Your Users’ Privacy
First and foremost, HTTPS protects your users.
Posting a news update on a user forum may cost a dissident his life in
an oppressive regime ; A strict workplace may terminate employment based
on an employee’s browsing activity; And of course, the Snowden affairs
have clearly shown governments simply can’t get enough of this data.Using
HTTPS makes it dramatically harder for these players to know what users
are doing, and helps you maintain your most important
responsibility — your users trust.
Browsers to mark HTTP as Insecure
Today, browsers mark HTTPS by painting the URL green or adding a lock
only if the site is properly encrypted. These markers actually convey a
false sense of security, stating HTTPS websites are secure when they
may be woefully insecure once you reach the server. What is accurate is that unencrypted HTTP connections are insecure.
Browsers are now poised to update their indicators accordingly. Both Google & Firefox have stated they’ll mark HTTP sites first as dubious and then as insecure,
possibly as early as this year. If you remain on HTTP, your users may
be explicitly told you are insecure, reducing their trust in you.
Note: The effectiveness of passive markers, positive or negative, is minimal, and browsers may evolve those warnings to actual click through warnings.
