Me when I develop something or test something with another ones tool or want a quick comparison: I don't want to use something in production for a while just to see if the basics are met.
Those sites give me the opportunity to bomb me with all kinds of scenarios and I check what's working for me and where not.
It's not about a few sites that I could quickly check but about patterns.
That's like saying the foreigners not having a vote is being not democratic though. Because 100% of the owners have voting rights not only a few.
I think what you intend to criticize is the fact that owners and "employees" can be separated, right? If yes then I'm with you.
