This is absolutely incorrect. "Every piece of software" is completely bogus in every respect.
I am a designer/ illustrator that exclusively uses GIMP & other programs that are not only free to use, but they do not incorporate any kind of gen-ai tools, they will not be force-integrating them (unlike adobe), and they are very aware of their user-base, who doesn't want it in the software they are using.
There are countless alternatives to use besides the big names in the industry. Nobody can force me to use adobe tools if I don't like the way that company is doing business.
