The point is not that it is unfair. It is.
The point is this is how BA now operates. It is a money-making subsidiary of a giant corporate monolith (IAG), a monolith whose only interest is that its subsidiaries are profitable. IAG is largely uninterested in how those profits are generated. Emotion does not even compute. If you think it's likely to be much different once you're in, you may want to look elsewhere.
BA will recruit whoever is the most cost-effective for them. End of discussion.
