They claim it's impossible because they don't want to lose market share.

They didn't start treating women, black people, LGBT people, the disabled, and countless other minorities as human beings because they thought all human life has intrinsic value, they started treating them like humans because they realized they were leaving money on the table. They realized their profits could be even bigger if they hired people from these groups and aimed advertising at them, they could have everyone's money, not just white people's money.

Now that the real "silent majority" aren't a bunch of backwards fucking racists, companies try to act like they give a shit about various minority groups while really only caring to get the profits they can extract from those communities.

They understand that when they lose customers, those customers turn to other services to spend their money, with right wingers and white supremacists and authoritarians, that's running off to places like TruthSocial and Xitter.

This is the same thing, they don't value the lives of white supremacists, they value the money in their pockets, and as long as those people have money to spend, they will find excuses to keep taking their money.

The Fediverse easily sidesteps this problem by being volunteer and donation-based, meaning nobody is currently using it to sell to the biggest markets available.
