Boring reasons mostly.
Im told they offer better options for tiered monetization and the UI is supposedly way better. They also do a better job of promoting smaller creators.
Plus, they never threatened to oust their adult content creators because their payment processor asked them to.
For me, it was a number of things that all came about through my 20s. The biggest were learning both how and when to tell people “no”, and making a conscious effort to think proactively rather than reactively.
What I mean by that is don’t take on extra work only because someone asks you to, and if something goes wrong, only worry about it if you can actually do something about it. Both of these are skills that require practice.
Also, as others have said, think critically if it might just be a shitty work environment. If that’s the case, consider looking for other work while keeping this job.
