The OSI and FSF make sense by prohibiting stuff like the sspl. Open source should express freedom and by putting restrictions on certain users no matter how evil they are wont express freedom at all
You seem to be opposed to software freedom. The SSPL is a viral copyleft open source license, it merely requires users to open source things. The SSPL is only restrictive in the same way as the GPL is, it requires granting users software freedom.
Also, you're wrong. The FSF's position is basically that software that is non-free is immoral, so any license which forces additional software to be released with a free license is inherently moral. A very copyleft license like the SSPL should be the peak of the FSF's goals.
As said no. A license should not discriminate not even against billionaires. Either you start with x and keep it that way or you are not better than the billionaires. Bait and switch is even worse than being a asshole
