Why do freelancers always run from working on freelancing platforms?

[Btaliat]

As there are some people that are aiming to be freelancing on platforms, there are many of them as well that don't like it. Many have cited many reasons for this. For instance, some have said that they don't like the fact that they do charge some service fees, which is 20%. They see this as being outrageous. Others don't like competition. Because of this they don't like working on some platforms rather they prefer people referring them.
