Most of OP's claims can be supported or refuted by randomized trials.
For example:
> If a driver usually logs on at 10 PM and accepts every garbage $3 order instantly without hesitation, the algo tags them as "High Desperation." Once they are tagged, the system then deliberately stops showing them high-paying orders.
Find lots of drivers. Ask some to log on at 10 PM and accept garbage orders, others to log on at 3 PM and accept garbage orders, others to log on at 3PM and only accept high-paying orders, etc. See what kind of orders they receive after a while.
The drivers you select are biased towards enrolling in trials, but I doubt that's significant. Even if so, the algorithm showing certain drivers different orders, who don't clearly perform "worse" in a way the study could observe, already seems wrong.
EDIT:
> If the algo predicts you are a "high tipper" and you’ll likely drop $10, it offers the driver a measly $2 base pay. If you tip $0, it offers them $8 base pay just to get the food moved.
This is much easier. A single driver can provide strong evidence to support or refute this by showing the base pay and tip for their recent orders (AFAIK all apps show drivers these metrics). Unless someone (even a single person) has done this (on one of the delivery subreddits), there's strong evidence that OP is lying.
