Facebook is competing with other FAANG [et al] companies for talent, and not all of them are in the same sector. Their market position is only relevant in that it allows them to compete for the kind of talent that $300k a year can buy, and they deem it necessary for maintaining that position, they are not going to pay more than necessary nor are you entitled to more just because they can.

Why does it matter to you whether you make $300k at a company that makes $500k out of you or at one that makes $1m out of you? You would be doing the same job and either way being compensated at the top range of the market for the skills you have. I don't see the point.
