How would you have a Java class without allowing unverified software to run on the schools network?

I said unsafe software. I specifically said spyware. If you're caught running malicious Java code on the network, you'll be reprimanded. If you're running known malicious apps by Big (Ad)Tech, you should also be reprimanded.

And just because it’s state schools now we should be extra worried, the Texas gop has been working to systematically disassemble all avenues of public education

If they were to completely cut all funding to public education, it's the state schools that would disappear. Private schools, who already are not affected by this ban, would be fine.
