But if they were doing Asahi Linux for fun as a hobby, and if it isn’t fun anymore for a variety of reasons, then you really can’t blame them.
I have 0 knowledge about this project, so my statement here is just a general statement.
But if a developer collects donations for promising something, then this is not just “for fun”, but they do have a moral obligation to try doing a good job.
It seems they overfullfilled their obligations (but all I know about it, are the words of the developer). So, as said above, this is a general statement.
Many things are possible with both products. But Kritas focus is on drawing/paiting and animation, meanwhile GIMPs focus is photo edititing.
Just try them out. I really love both.
