The current marketing strategy for Bluesky is to target disaffected left-of-center people.

This isn't because Bluesky is the one moral company in all of capitalisim. Instead, it's because they see an opportunity to grow their userbase (and income) by messaging to people who are likely to leave Twitter. It's no different than the thousands of companies that put up Pride Month banners and then a month later they take them down and continue donating to right-wing politicians.

Bluesky isn't your ally, they're just the current company that is pandering to you.
