Weightlifting got beyond fucked by scandals. Sure, every sport has scandals, but name one other Olympic sport where the president of the international federation got accused of tempering with the anti-doping process and then got a lifetime ban from CAS. You can't put that just aside and pretend like it happens in every Olympic sport. The Aján scandal tarnished the sport.
The boxing scoring system is shit, makes it waaay too easy to cheat, not to mention that AIBA also fucked that sport and maybe it never recovers. All other Olympic combat sports have much better scoring systems with VAR in place to question every decision. Boxing is in its current state doesn't belong to the Olympic Games, it's more of a performance art of "who can perform the more visible punches for 3 rounds" than an actual clear combat sport.
As for wrestling and rhythmic gymnastics... GR wrestling will be thrown out if they won't introduce women's GR. And RG has to introduce male athletes like artistic swimming did. Other sports are doing their gender equality homework while these don't, and there will be consequences of that eventually.
As a Hungarian I want to keep Greco-Roman wrestling alive, but they are so behind the curve on gender equality that it might already be too late. It's like the wrestling federation isn't even trying.
