If you advertise a product or service to include a special offering (IFE) if one chooses to do business with one company (AC) then it is reasonable to expect to get the services as advertised.

Anything short of that is reasonable grounds for compensation.

AC is NOT a commodity, they are premium full service Canadian airline brand (their words not mine), and if they can't live up to their own brand promise, then they should revisit their offerings and prices.

Until then, let the compensation continue.
