Can you give some examples?
I feel like that's not the case: eBay, AirBnB, etc are some of the iconic marketplaces and create massive income opportunities to people who didn't this option before the platform existed.
It's not unique to TripAdvisor, but they're a 800lb gorilla in that market.
This is even before considering how they squeeze gig economy riders.
I know several eBay merchants. They all gripe at the high fees, ever-changing UI and rules, etc.
Recently ebay bucks was reduced from 2% to 1%, and now sales tax is collected across all purchases.

Are you a shill, or do you believe all the PR?
