People rip off our hard work, what do you do in this case?

We seen a product launch on Product Hunt and then found that many of the things are a copy/paste of our own product https://www.creative-tim.com/product/soft-ui-design-system-pro

My message to them:

"Hey guys,

Congrats on the launch, we checked the builder and it seems there are many things that are simply a copy/paste of our product which was launched 8 months ago: https://www.creative-tim.com/product/soft-ui-design-system-pro. In the beginning, we thought it’s a simple coincidence as these sections are usually similar in this ecosystem but then we saw that you took our own texts (which are a reinterpretation of Kanye Ipsum (http://www.kanye-ipsum.com/), which is different from "Lorem Ipsum" that most templates creators use). So even if you copied from Kanye Ipsum it’s impossible to be the same texts...

Here is the first example

1. Original Text on Soft UI Design System and Copied Text on MDB Builder: https://imgur.com/a/n7XDjAu. Title description buttons are identical.

Then we took a closer look and found the code that is for the “gentle-wave” is the same as us, we used it from a free source on Codepen but we extended it, with our own values. We found the same values you have in your product. So you took that from us, not from the original source where it is open source.

2. Codepen original code Free to be used: https://codepen.io/goodkatz/pen/LYPGxQz - 4 waves with opacity 0.7, 0.5, 0.3
3. Creative Tim Interpreted version: https://demos.creative-tim.com/soft-ui-design-system-pro/presentation.html - 6 waves with opacity 0.40, 0.35, 0.25, 0.20, 0.15, 0.95
4. MDB Editor copied code from Creative Tim: https://mdbootstrap.com/presentation/builder/ - 6 waves with opacity 0.40, 0.35, 0.25, 0.20, 0.15, 1

Then there are other examples like the pricing section or headers that are 1-1 copied.

Features: the hr vertical w/ opacity has the same code as us: https://imgur.com/a/vhebzNf

More copied sections can be seen here: https://demos.creative-tim.com/soft-ui-design-system-pro/sections/page-sections/hero-sections.html

Don’t get me wrong. It’s perfectly fine to get inspiration, to add things on top of that and improve, but it’s not cool to rip off our hard work of 6 months. Hope the community will understand and will not support/upvote this kind of thing...

Best,
Alex"
