It's not monopolization when you can just buy the alcohol yourself or (in AU/NZ) the supermarkets themselves do alcohol delivery. I'd be surprised if more than 1% of all alcohol is delivered by Uber. To use monopolization like this is to strip it of all meaning.
Afaik any food delivery app can also deliver alcohol these days, so I am not sure what the whole monopolization hubbub is.
And for all it’s worth, it is much easier dealing with UberEats or Doordash customer service than it used to be with all the fragmented separate small apps. So as a customer, it definitely feels like a win.
