About the license... Rated 1 out of 5 stars
I've read your replies to criticism towards the license and quite simply it did not provide any more trust for you. I am not beginner nor even just average user when it comes to understanding security issues and how to avoid them - it's in computer security 101 that you should not trust little known 3rd party software provider for his words if other things, like obsucre license terms, seem otherwise.
You say that you could not use screenshots of other users comments without the criticised part of license - I say that it's a lousy explanation as you could easily change it to state that you have just rights to show users comments on screenshots on this plugins web page.
To put it simple I have no way knowing if you can be trusted and while you could be most honest people in the world I will never accept that license term - but if you ever change it I would be quite interested to install this plugin and try it out. If you have honest intentions then I recommend you to consider this throughly as that way you can get me and other people who will never accept current license to make U-turn and have us install this plugin.
P.S. Unless you realise that you don't need that large rights to use our comments for your needs and that users generally like to keep their rights to their own writings you don't need to reply my comment - there is no way I will accept that license no matter how hard you try to justify it, not even if your justifications would actually be correct.
