Would you be okay if LinkedIn and GitHub banned your account without any explanation? Or are you of the opinion that it's not a possibility because you follow all of their ToS to the letter at all times? Do you admit that you'll never provide any objective feedback about these companies since that may (or even should?) violate their ToS in your opinion?
It's interesting that you immediately assume that she's actually disparaging LinkedIn in any way, without any such proof being available. Providing any critical opinions whatsoever, about the company as a whole, is now disparaging the individual employees of the company? Why are you disparaging the author of the essay? What if she's your colleague, too?
You might want to check your biases if your first instinct is to immediately assume anyone who's been wronged in any way by any bigtech platform is immediately an entitled person by having an issue with such an action, and is doing nothing more than disparaging the colleagues of yours.
How can you be sure that the person who's been deplatformed is not a colleague of yours, too?
Why is it okay to disparage private individuals in private capacities (and to deny them their livelihood in these cases of LinkedIn and GitHub bans), but not okay to provide less than ideal feedback about monopolistic multibillion-dollar companies?
