I think Pippa is in a good place mentally/emotionally.
I agree with this 100%. She's been able to hangout with friends in person, she seems to be getting along with family at home, and work doesn't seem to be too stressful.
However, I can see what they're saying when it comes to her streams. "Happy" doesn't really fit with how I think of it. I think the best word would be "comfortable." Pippa isn't rocking the boat intentionally (but Christ you look at the people she bumps into online you'd think it was on purpose).
One of her streams a week is a chill MMO stream, she's not really covering stuff that's too controversial (moon landing conspiracies that she tangented on but refuses to do a stream on it), and some collabs (semi-derogatory, except for Marimari_en and Kirsche ((of course)). I get why Pippa wants to try and keep a good image, but I can understand why people think the streams have become stagnant.
tl;dr Pippa should say the N word on stream.
