* remote work widens the competitive playing field. Boo hoo. If you think non-remote work is somehow immune to offshoring, take a look at the last three decades for counterexamples.
* remote work enables you to be forgotten: sure, if your managers suck. Again, see gestures at the entire industry for examples of people getting "forgotten" at in-person offices.
* remote work breaks large companies: better phrasing - "remote work makes it plainly obvious that large companies are broken"
* remote work can stifle your career growth: again, sure - if your managers suck. They likely suck in person too, in that case.
* Conclusion: "what if instead of remote work companies just stopped acting like companies act"
As a content marketer, Sean is doing a great job of supporting a target customer persona: sucky bosses who are desperate to find a way to get back to an arrangement that makes it harder to spot how much they suck. I'm sure he'll get a lot of clicks.
