I remeber when the Boruto DB first came, I even created the first thread about it here.
Because Sarada had more than "just punching" in it, Boruto fans got rustled and started to undermine her potential, especially because she's WAY better than Boruto, stat-wise, in it.
Back then, Sarada hadn't had much screen time so her only feat was CES. People (Boruto fans, to be exact) were ditching the DB and saying Sarada would never do anything more than just punching, because she was simply a "Sakura 2.0" - even though she had Lighting techs in the DB, they were denying that - and many other people were co-signing Sarada's undermining by Boruto fans. And they kept preaching the same shit until last year (October), when she finally showed Lightnining in the anime.
Why Boruto fans get to undermine Sarada's potential, but when the same happens to their dear Boruto, they get emotional? I will never understand.
