As someone who mainly plays Ubers, hazards are still a pain. However, they are a bit easier to stop because the only ones who set hazards are Ting Lu, Clodsire, and various supports Arceus forms. These are the most common setters and well, Arceus now has taunt so it is often worth maximizing speed just to spam taunt. The second best mon, Miraidon, also has a boots pivot set that runs taunt and its really good into Ribombee leads because it can't set webs. However, hazard removal is a massive problem and the best way to deal with it is simply to dael with it. Both sides will die to hazards anyway. The only real hazard removal is is Origin Giratina but that invites in Arceus to just set rocks back up or use it as setup fodder for calm mind. Iron Treads is an option but it's really only useful against Miraidon. If you're not facing Miraidon, Treads can feel dead weight
Aside from that, Ubers is such a centralized tier with many mons repeating themselves across nearly every team. You have your Koraidon, Ting Lu, and Arceus form. The rest are a mix of Zacian, Kyogre, Skeledirge, Toxapex, Flutter Mane, Eternatus, and above all, Miraidon. Koraidon is so dominant with its scarf or scale shot sets that it even had a
69%, nice, usage
So, to answer your question, yes, hazards are still bullshit but not for the same reasons here. I don't play OU that much but from what I understand, the issue with hazards is that removing it is nearly impossible due to one pokemon being such a pain. In Ubers, the issue is that we literally only have one pokemon that can remove hazards that also isn't too reliant on matchup, Origin Giratina
