So, your answer now is to argue that you don't know whether or not the working conditions are bad, after arguing that they aren't bad enough to entitle people to complain?
Which is it? Why are you now equivocating over this instead of being able to answer for your own conclusions?
Clearly you think the working conditions of Twitter aren't that bad, that was literally the thesis of your first post. Clearly you think that there exists a set of working conditions that are deeply immoral and deserving of at least complaint. That was also the thesis of your first post.
So where does that line exist? When do working conditions go from "not deserving of complaint" to "complaints are fully justified"?
