I can't accuse Bravo of any definite motivation but their for profit desire to sell their advertisers. However, a possible motivation in cutting the love scenes to the point that only the sexual activity is left is this: a desire to cast same sex love entirely within the context of sexual gratification and the elimination of any romantic aspects of their relationship. Why? To influence the debate over same sex marriage among the voters in CA leading up to the November ballot.
Some of the long term goals of the religious right are to de-legitimize same sex love and forestall same sex marriage. If the appearance can be created that same sex love is just about sex and only about sexual gratification, then the religious right can make the argument that marriage is inappropriate between two members of the same sex.
This is why this "editing" is important, and why it is esp important that it came about only 3 months before the CA voters go to the polls.
If it had just been changing Jack Fuckin' Twist to Jack Frederick Twist, this would be funny, but the almost entire elimination of TS2 points to a possible agenda, and I might add possibly a hate-filled agenda.
