Very few, if any, fans were screaming that they 'want him sold' as you're portraying here. What some were saying is that IF the opportunity came to upgrade on him then it should be something that is considered, which, in light of some of his goalkeeping over the last couple of seasons, is a very reasonable thought process to have I would have thought.
I haven't listened to any pundits opinion on Lloris, I've watched him in every game he's played for Spurs and seen he's been quite clearly gradually declining, his distribution from the back(a vital part of our game) is appalling and he makes more glaring errors than any other top six goalkeeper.
Of course replacing him isn't a pressing issue in the slightest compared to our other problems, but I would hope within the club there is at least discussions going on about who his successor will eventually be.
