This is key to understanding bipolar: it has an "upswing" phase in which someone has more energy and less inhibition. Increased self-belief as well. It can, if you're lucky, be just the right thing to catapult someone into incredible creative works.
The risk is that risk-taking may not pay off, and the inhibitions may have been there for good reason. Not to mention that there's also a downswing phase which looks like depression and comes with elevated suicide risk.
After a few major life disasters (including getting married, and then having it annulled), she eventually figured out that the highs were fun but dangerous. I haven't talked to her in years, but she was reliably taking her meds to keep her even keel.
My friend was pretty self-aware though. Someone less so may not be able to see that their illness is the true cause of their life disasters.
Anyone who has dealt with/supported folks suffering from mental illness (and I definitely qualify, there), will tell you that mental illness gets worse, as you get older.
A young man that compulsively washes his hands, may well end his life, flying around the world in a sterile airplane, keeping his piss in canopic jars.
It's possible that he's exhibited symptoms for far longer but it was brushed aside under the guise of kooky genius. I mean, the Taylor Swift thing was, what, 2009?

I’m of the opinion he’s both someone with good intentions with good points but who makes those points sideways. But also that he’s mentally I’ll so he’s losing the ability to communicate clearly. I also think Candace Owens is an untrustworthy person with only self serving intentions.
It’s gone now. Memory holed.
Whatever is going on in this individual case, Bipolar disorder is terrible. It can look like someone is "fine" for a long time, but then they aren't fine and people look for what changed, and what changed is progression of the disease.
It's really hard to talk about without adding stigmatization.
Ya know.

MBDTF came out in 2010. That was around the beginning of social media entering the mainstream (Kanye joined Twitter in July 2010).
So up until MBDTF, he didn't have a device in his pocket that allowed him to broadcast his unfiltered thoughts to millions of people. Up until that point, his public image was likely carefully managed by his label and management. All of his interviews were probably overseen by them. They likely only allowed interviews where he was asked pre-approved questions and gave canned answers. If he went too far off script, his label likely stepped in.
It's clear now that he has a lot more freedom with handling his own image. He's been signed to his own label since 2016 which probably afforded him a lot more power over his career. He had a few moments prior to 2016 but he didn't really go off the deep until 2017.
TLDR: what you saw as stable behavior prior to 2017 or so was probably the result of a curated image created by his label and management.
Devil's advocate: there's no way this isn't the case for Kanye, right? Why is this mental illness sparking up later in his life? Why was he able to achieve everything he's achieved 1996 -> 2012 (Roc-A-Fella -> The College Dropout -> My Beautiful Dark Twisted Fantasy era) without these "mental illness" bouts?
