Wee One,
You might be right. But your earlier statement seems a bit unfair on our Eastern European colleague who is on 1400 euros a month. Imagine yourself in their position and you might have done exactly the same.
Different people will make different choices based on their requirements. I do understand what you are saying and personally I wouldn't join either. But if you have the choice to join OS or be without a job in the near future then a lot of people will choose OS. And hopefully I will never be put in that situation but I might choose OS also over being without a job.
Very difficult to judge the people who have joined and what their reasons are.
But I must add, that unlike you, I don't know anybody who has joined OS.
