Idk why bother when they could literally just use OF

because the aforementioned website is known almost exclusively for porn.

Some, maybe most, people would be fine with it, nothing wrong with it really.

But if you're trying to earn a living why cut yourself off from the 50% of people that wouldn't subscribe due to the site name only.

Besides the association, which one might or might not be fine with, I'd worry that being porn-centric would put OF at risk of credit card companies not wanting to work with them, similar to what PornHub faced recently.

OF is blocked in my country.

the main thing is that onlysponsers does not take a cut and it is integrated with github sponsers for payment and sponsorship tiers

OF has high fees afaik.
