Sri Lankans are being bitter losers by complaining about the squash ball trick !
If anything, Gilly's squash ball trick was used to change his batting style from playing square of the wicket to playing in the V.
People, and the complaining Sri Lankans, should realize that putting a squash ball in your glove makes it extra difficult to play your strokes. In that sense, it's a handicap and not an advantage.
People should also realize that Gilly has the ability to play square of the wicket as well as in the V. It's just that he has been getting out of late while playing strokes in the point region that he decided to use a squash ball that would force him to play strokes in the V.
