That's...an interesting perspective, but I think the audience is expected to already view love with that importance, so that the love storyline instead underlines the power of the control of the state.
Similarly with BNW. I think you are reading things that the authors perceived and sought to leverage in their contemporary audience with as being instead the message of the work: neither is about love, but the effect the dystopia described has on love is a key part of painting the picture because of what readers are expected to already feel about love.
My takeaway was that love was the most important emotion yet the state has the power to control even love. I don't think we're supposed to believe his love for Big Brother is genuine, but rather manufactured much like revisions to history.
Except that she doesn't love him and she immediately and fully confesses everything and betrays him.
The book is about the political classes, while the majority of the population (the proles) are not discussed a lot, they seem to have simple lives and can love.
All of the Big Brother, Ministries of Whatever, censorship, and surveillance stuff was just window dressing for the love message.
Even Brave New World, to me, is about love. The society spurns familial love (like between John and his mother) and committed relationships (like between everyone and everyone) and pain or discomfort is a prerequisite for love and the pursuit of happiness has all but eliminated true love from the world. John kills himself because he hurt the woman he loved, he is humiliated for loving his mother, and is frustrated by the fact that the woman he loves can't love him because she is too busy pursuing simple, immediate, pleasures.
At least, that's my recollection of the two books.
