I think there are interesting fundamental objections a lot of people seem to have.
Labour laws and conventions almost assume people do not have a choice in their place of employment. That's why a barman's right to a smoke free workplace is more recognized than a patron's. With that in mind I think people feel that employment needs to be accessible to everyone and that this is specifically designed for young singles.
There is also an objection to the cultish nature of this, the opposite of work-life balance. If an employer controls your work life and your home life… I think that's what rayiner is objecting to.
Think about it this way. In one case you have a high priced escort who takes on a select few clients and earns like a star stockbroker. On the other you have a lower end prostitute earning less, in worse conditions and probably and with all the associated social problems of prostitution. To many, they are fundamentally the same thing because being a hooker is the important part, not the consequences of being a hooker.
I'm glad to see experimentation like this. I think if some people really like it, that might outweigh the other cases where people dislike it. In the midst of such a demand for programmers, they should be able to leave.
