There's plenty of outrage about paid loot boxes and viewing them as terrible, terrible gambling that exploits consumers and ought to be regulated/banned. Not everyone agrees with this take, but it's still fairly widespread.
Now, you do see people pointing out that trading card games are basically still gambling -- and no one really disagrees with that -- you just don't see the same level of outrage about it. What you usually see is grudging acceptance, ala "what're ya gonna do, that's just how these card games are".
