I definitely think the current outrage around "Big Tech censoring free speech" is a downstream effect of these companies curating feeds to maximize ad revenue.

I definitely think the current outrage around "Big Tech censoring free speech" is a downstream effect of these companies curating feeds to maximize ad revenue. If these platforms presented the content without interpreting and curating it for profit, they could at least take the stronger stance of being a platform instead of a speech curation/distribution/amplification system. For example if Signal was externally pressured to take down speech based on its content, they would be like "We don't have that ability." But in the case of Twitter and FB, that ability and practice is at the very core of their business model.
