I have used Photopea somewhat, but I have thought this is temporary as it's not open source. How long this will be available? If Adobe targets this, it wouldn't be a surprising to see this being bought off and killed.
1. Nobody can buy Photopea, if I refuse to sell it.
2. I am not aware of using a work of someone else, or a unique idea of someone else. I would not be able to live in a world, where I am constantly scared, that someone more powerful can put me in jail, just because they have more money for lawyers. I hope our world is not like that, and if it is, I am ready to fight to change it.
