The yeshiva I went to had English on Sunday.
I suspect the communities in question would dispute that as the purpose of their school system. They would probably say the purpose is to teach Torah.
In which case they shouldn’t be milking the government for funding. But that’s old news, just like the days in yeshiva when they’d give extra special lunches and tell everyone to smile because the inspectors were coming; we thought we were playing dreidel so the yevanim wouldn’t kill us, when all along we were simply assisting the school in cheating the government into thinking they actually use the lunch money for lunch.
