I remember people welcoming Uber not because of the app, but because the idea "you'll know exactly how much the ride will cost you before you take it" was revolutionary at the time. Over here, what used to happen was that you order the taxi, the guy says "yeah I'll take you there it'll cost you $10" and then the bill was $20 and there was nothing you could do about it except pay. It was completely normal for taxis to scam people. So when Uber came and started scamming drivers, everyone cheered.
The point is, you're essentially right. It's just that before Uber customers were most likely victims of scams, while with Uber it's the drivers. As in, in a capitalistic market the scamming is always present, the question is who scams who.
Scam is too generic of a word... its information asymmetry. Also for the most part everyone is trying to get some service/product for the lowest price while at the same time trying to earn as much as possible for some labor.
