A better question would be - what DIDN’T they cancel? Here’s a list of Netflix Originals they cancelled:

That list also doesn’t seem to include shows that were informed they were getting cut, so ended it prematurely.
Your comment is talking about Christians and Muslims in general, there’s nothing in there that indicates you’re talking about the population in a specific country. Nor is the comment you’re replying to referring to a specific country.
Even giving you that, I find it hard to believe. The only reason the Muslims aren’t behaving as you say the Christians are is because they don’t have the authority or force of numbers. Name a single religious majority worldwide that doesn’t push their values onto nonbelievers.
The biggest obstacle to a YouTube competitor is that YouTube themselves can barely turn a profit. The operating costs are ginormous, beyond what most people realise.
