> That's why Udemy remains an attractive option (despite how badly Udemy treat authors as you say). It's a bit of a chicken-and-egg situation.
It is but at the same time it's not.
If you make a course in a category where there's 500 other courses which is the norm for a lot of tech niches you'll be on page 30 and no one will ever find you. For new courses Udemy might decide to show your course to a tiny percent of traffic in a higher search ranking to see if you gain traction but unless you drive your own traffic to Udemy from your own site / resources you're going to have a hard time competing with folks who do. Their algorithm very much prefers instructors who send their own audience to Udemy.
If you don't gain that initial traction you're basically dead in the water. Plus it's going to be a hard sell to get someone to sign up for your course with 4 enrollments and no review vs courses who have 100,000+ enrollments and a 4.4+ rating.
With that said, having no audience won't help much on Udemy vs being on your own platform. You're still going to need to grow an audience and send traffic to your course landing pages no matter which platform you use (a 3rd party marketplace or your own site).
