Saw an interesting mechaber recently. Hilchos shabbos. dont have the siman offhand, halachos of business on shabbos.
It is mutar to hire someone (some say even discussing an exact price) to teach your son a profession on shabbos.
I believe it is the mb who explains that it is a dvar mitzva, because if you don’t, he will steal from people.
To be fair, I believe the biur halacha explains that this doesn’t mean that learning is bad.
It is hard to justify a protest against a dvar mitzva though.
