Not once they reach a certain size, no. It turns into a pointless exercise in moral relativism. Joe brings up the Soviets, Jane counters with the East India Company. Bob rants about Trump, Betsy pulls up the Wikipedia article on Union Carbide. Sally complains about police brutality, Sam lectures her on the history of the Pinkerton Agency. Hank sticks up for the UAW, Mary criticizes the Teamsters.
None of these organizations should have been trusted implicitly to do the right thing for society at large. The burden of proof rests decisively with those who want us to believe that Google and Facebook are somehow different.
All of these organizations operated at their zeniths during different time periods, governments, cultural norms, and a variety of other factors. The problem with the conversation you're describing isn't moral relativism or that everyone in it has equally valid points, it's that none of them seem to be capable of isolating the elements of those organizations that functioned/dis-functioned without endorsing/criticizing the organization as a whole while still presenting a cogent argument.
You don't think any organizations have ever been any more corruptible than any other organizations?
