No issue with them and I know a number of players who went close to giving up the game as their putting was killing them so went to either a broom handle or belly putter and found a new lease of life
They aren't be banned and can't see why they are an embarrassment
If the item allows people to carry on playing then have no issue at all with them
They have been around for decades
As soon as a few people win a major with them ( think its 4 ) you hear cries of unfair etc - if they were that much of a help then wouldn't expect to see a lot more using them. Don't think the use of them being anchored should have been banned
