There is absolutely nothing wrong with plugins or scripts or Extensions being similar.
There are scumbags who have accused me of ripping off other scripts only to start selling even more similar products than others I have developed!!! Colors, Shape Layers, Text Layers, LUTs/ColorFX etc etc etc, all, can provide similar results. If the UI is different and even if they provide identical results in all use-cases, the one with a better price and/or is more performant at the same price; should be the better product.
A different UI will invariably allow a user to create different effects. And just because someone came to market earlier doesn’t mean they were first with the idea. Not everyone has the time to develop products. And it has never been about a race, to market first.
There is this destructive mentality going around for a long while that anyone that comes out, first, with a poorly executed product should monopolize market share, perpetually – and amazingly, this extends to highly versatile tools such as Text Layers, Shape Layers, LUTs/ColorFX.
