Sadly I think this is the new way of doing things. It gets more and more acceptable to crucify people using social media. But at the same time I don't agree with your conclusion that this makes it right for Medium and Github to remove this. They should keep out of the judging/censoring business. Steam is sadly the only good example of how it should be done at the moment.

Edit: Because really otherwise they should remove the information from LinkedIn (or make it non-searchable) which also makes it very easy to get and they don't do that.
