I don't think the point of this is to say that all of Tapas' series are identical. I'm sure the series that Tapas buys are plenty enjoyable, and have teams that work very hard on them. But what this thread proves very succinctly is that there are absolutely homogenous themes and art styles that run through Tapas' premium library. The fact that someone can make multiple shockingly large collages out of how many times they find the word "Villainess", or all the identical male leads on Tapas' front page is telling.
Tapas has a very distinct brand language. They have a very specific audience that they serve, and pretty much nobody else. The point isn't to disparage these premium creators, but rather to point out that Tapas serves only a single demographic, and that's it. For those of us who aren't interested in that content, or who are creating content outside of that very specific box, we're left feeling alienated. There are hundreds of vibrant, varied, and unique comics on the Tapas site, each with dedicated creators that work just as hard as premium studios, many with actual professionals behind them, but they will never ever rise to premium status on Tapas, because they don't fit within Tapas' incredibly strict brand identity.
