mmmm Its pay if you want to pay. Again, morals aside, you don't NEED to pay for it.
Rizzler This is a paid software with an infinite trial essentially.

My understanding aligns with @Rizzler as follows: FUTO makes the software available under the condition that users pay, though they know users can use the software without paying. That is not the same as "pay if you want to", as follows. If some large company installed FUTO software on work devices given to employees without paying FUTO, there would be clear grounds for FUTO to sue and, though I am not an attorney, I believe it is likely that they would win.
In theory they could also pursue individual users, though in practice that wouldn't make sense... except maybe to embarrass some high-profile wealthy person using their software without paying.
But overall "what is legal" and "what you can very likely get away with" are not the same thing, and the difference isn't just "morals".
