One of the goals of source first licenses is to stop enshittification since it doesn’t allow paid clones

Copyleft prevents enshittification much better than anything in their license. If someone makes a paid clone of some, for instance, AGPL 3.0 program, one person can buy it and release the source code of the paid version and then all of the improvements can be incorporated back into the version from which it was forked.

Unless the paid clone makers go so far as to break the terms of the license. But that’s not a problem that the Grayjay license solves any better than the AGPL 3.0.

Grayjay’s license is itself a textbook example of enshittification.

Not saying I agree with their policy, but I would hope more for-profit businesses make their source code available

I’m not pissed at FUTO for releasing their source code under a non-FOSS license. I’m pissed at them for doing everything in their power to sabotage Open Source specifically to serve their bottom line while also pretending they’re some champion of consumer rights in tech. And it’s really shitty to use a .org address to further drive home the lie that they’re anything but a for-profit company fucking over consumers to make a profit.
