It's just moaning about the bad UX deliveroo has and using made up figures.
All he says is that he's guessing 5-10% of people tip, and the default tip is only 10% therefore the gig workers are only getting 1% on AVERAGE.
It makes no claims of stealing, there are ZERO articles on the search backing up your claim, and only a few Reddit posts from riders who thought that maybe one-time, deliveroo didn't give them their tip in a complicated set of circumstances that was probably simple user-error.
I'm not a fan of the gig economy, I know the previously some other companies in America stole tips, but you've made a totally unsubstantiated, libellous claim about Deliveroo there.
This is part of the reason why there's this whole struggle to define what exactly the gig-economy worker contract is supposed to look like, because they're not paid hourly and it's often net negative for full-timers, who do exist.
Also to clarify a point made in the article; this is not the equivalent to a tipped wage. With a tip wage you already know what your base pay is up front, and tips are additive; what DoorDash was doing was deducting tip from some set base pay. Fortunately I live in a state that does not differentiate tipped and regular wage.
