I would have agreed with him if that added a “taker tribe” keyword to all units in the army. Other battle tomes specifically allocate keywords to all units based on their sub-faction. But sons does not, it gives you access to additional abilities based on your generals keyword. The sub faction keyword is not “KRAKEN EATER”, and no other unit in the army has that keyword unless you have taken an army of kraken eaters. But hey, TOs are free to rule as they like, but I would challenge it as not being RAW, and unlikely to be RAI. As if that is how GW had intended it, they could have just continued their practice of allocating a keyword to all the units in the army.

For 27.4 to bite the general needs to have the sub-faction keyword. To the best of my understanding tribes do not add a keyword to a sons general or units.
