She should say "No one likes Gaga" because saying "no one cares about Gaga" means she wouldn't be talking about her. I don't even like Gaga, but being disliked is different. Gaga is still a known name that generates headlines, it's just that majority of it is negative and people no longer like her
As I've always been saying, Lady Gaga has fully exhausted her shock value. That was a big factor towards her early success, but she exploited it in such a short amount of time that she became old news. She was such in a positive trajectory, but anyone who denies that she's on a downward spiral is deluded. She doesn't have the star power she used to have.
It's kind of funny how y'all throw the "Then why is she talkin bout Gaga THEN?! Huh?! She's so irrelevant!" at her while you guys all stream her damn video, mention her name and discuss her opinion, which, in turn, makes her more successful.
