Firstly, uBlock doesn’t really talk about its own updates, since all the frequent updates it needs are provided by its filter lists. It’s basically an app store, a little bit like F-Droid. And you’re right, I can find no explicit language that either states or implies any of the things i listed.

But think of it this way. There is a prominent link to their list of releases, <https://github.com/gorhill/uBlock/releases>. From what I can tell, the releases vary from a few days apart to maybe a month apart, with the most recent release being yesterday. What would you think if, say, six months from now, there still wasn’t a new release? No bugs fixed? And, when asked about the absence of these things, if the developer’s answer would be “You’re whiny and entitled, I have no legal obligation to do anything, read the license LOL.”? I mean, he’d be technically correct, it would be legal for him to do this. But would it be OK? What I am arguing is that it would not be OK, and that users do have legitimate reasonable expectations of any project that presents itself as being active; i.e. fixing bugs, security holes, and implementing new features. Users are not “entitled” when expecting these things.
