I can empathize with you. You don't need to go on the attack/defense, you need to move and regroup your forces.

I don't see how you stand to benefit from writing a negative article.

The problem is no one knows who you are. The first thing we hear is you attacking Udemy from a defensive posture.

If you're going to present yourself to the world, I think the best way to do so is to show them who you really are. Tell your story.

So how about we take this off the front page, then make a new post about how great your tutorials are, what value they bring... and starting immediately, they can stripe/paypal you and buy them from your website for the best experience.

You can put up a paypal button now and email the videos by hand. Since you made a flask SAAS tutorial - you will probably be able to have a full video site up in a week or two.
