Meghan is a television presenter. The key professional attributes of a successful television presenter are the ability to give a warm, natural, charismatic performance on camera, even (and especially) if they have reason to believe that some of the show's viewers may have critical or negative opinions of the show.
The ability to 'shake it off', get on stage and knock 'em dead is literally THE job of a television presenter. Scratch that - it's literally what showbusiness is all about! People who cannot do this - don't get into showbusiness!
Meghan has the luxury of not having to be a television presenter. She's not a coal miner in the DRC with a bad back and failing eyesight, forced to do a painful and exploitative job because she has no other option. Nor is she a frail amateur who needs patience and forbearance, like a child nervously giving her first violin recital. She is doing a job in which she has a great deal of experience, presenting on a subject about which she says she is passionate.
In the world of streaming, we viewers have a multiplicity of viewing options. It is Meghan's job to seize our attention by giving a strong, excellent performance. She owes us, the viewer, an interesting show. We owe her nothing, and since she is immensely privileged and does not need to do the job, we don't have to give her patience, forbearing from making negative comments in case we hurt her feelings.
If showbiz is too intimidating for Meghan then she should not be in showbiz. Simples.
