Sure you could count every instance of someone not getting their will, which is unavoidable when decisions affect more than one person, as tyranny. But I don't think that's a very useful definition.

Sorry, I should have added a link in the previous comment. I think this is the reference: https://en.m.wikipedia.org/wiki/Tyranny_of_the_majority

I'm not trying to define anything, just trying to explain the reference.
