The sex workers aren't legally speaking staff. It's a platform that takes a cut like all the app stores.

It’s not exploitation unless the participants in the deal are being coerced. You can’t make a solid case for employees being coerced to work for an exploitative employer outside of company towns or non-functioning labor markets; neither of these apply to the Philippines.

If the chatter thought the job was so bad, they can quit and get a different one. Millions of people make that choice, it is available to them. There is no requirement that they do this work; it is entirely voluntary. The people doing these jobs have determined that it is the best option for them, personally, or they wouldn’t be there.

PS: $2-4/hr is a decent wage in the Philippines.

Under capitalism, man exploits man. Under communism, it is the reverse.
