That makes it easy to support raising awareness about it, which isn't scary at all.
> I would go so far as to say there should be laws or regulations preventing shadow banning/deletions
Nope, don't go there. The government is a huge hammer and they would love the opportunity to take this win from you. If you start making exceptions to the holding that "code is speech", then eventually you're going to lose something you care about that the government is after, such as encryption. And, a law that "bans encryption", which we all know isn't possible, would just further entrench existing power structures. The law would be arbitrarily applied because you can't ban math.
The same is true for banning shadow moderation. Either the behavior will shift overseas, or local companies will skirt around the written law.
Ultimately, society will have to accept that only individuals can hold individual decision makers accountable. We are each our own worst enemy, and each our own best advocate.
And, it takes less time to build Reveddit-like systems that apply transparency to existing social media platforms than it takes existing platforms and power structures to alter their behavior or grow userbases for new platforms. You need to flip your thinking. They don't have the power to control you, you control yourself, and therefore you have the ability to challenge the status quo.
