Well to be honest, tools to replace a calculator OS with another are legal, as that OS is freely available on Casio's site. The action of changing a cheap calc into a more expensive one is another story, but since the softwares to replace the OS are legal, then I doubt Casio can do much about it.
However if somebody decides to leave because 2072 ever decided to remove links to ROMs or software keygens, then I would find this unfair, because by letting such software on his site, he could get in trouble and his site shut down entirely.
Regardless, it's his site, though, so he can run it however he wants. On most calc site admins have to draw the line between illegal/copyrighted material sharing and other stuff, to ensure they do not receive a DMCA takedown notice from a company or another. After all, the TI community members got a DMCA takedown notice from Texas Instruments just for sharing the RSA keys, and it happened with ROMs and OSes before.
The thing I would recommend though cfxm is that if you ever go to Omnimaga, you can post links to tools allowing people to turn their calc into another, but links to modified OSes that contains copyrighted material will be deleted too. Please use .ips patching tools for such file sharing there. I do not want to wake up one morning and see the calculator website with this (and I think that might be what 2072 is trying to prevent with UCF):

Btw this has already cost Casiocalc's biggest source of revenue already. If 2072 was to ever run into financial troubles, then this means he may no longer be able to afford to pay the UCF hosting bill. Let's not be selfish here.
Rules that haven't been enforced recently (mainly due to my lack of activity on this forum). This lack of compliance has just cost casiocalc.org its advertiser and therefore its source of revenue.
