The problem with "speaking truth to power" is that the shitbags in power already know the truth (that they're shitbags, and that in a just world they would be torn down and humiliated, if not destroyed). What you do by "speaking truth" is reveal to them that you also know this. By doing so, you make yourself dangerous to them. Sometimes, this is what you want. Sometimes, it is not. It is not an easy, one-size-fits-all decision. Your enemies, but also your friends, start to see you as an instrument of war.
Also, with regard to "algorithmic demons"... it's not "algorithms" that are the problem. It's (a) the complete lack of transparency, (b) that the algorithms are often tailored toward objectives other than content quality (which leads to gaming, hence the perceived need for opacity), and (c) that the data now available about us is invariably used against us by bad actors (and that a lack of influence / platform will also be used against us, so I don't know if there's a way to win).
The algorithms themselves aren't so bad; what's worse is that these companies often slip shit into the algorithms that punishes people or ideas they dislike, and of course (a) this is completely unregulated, (b) it's impossible to prove, and (c) you'll often damage your reputation if you point it out (since you sound identical to a crazy person who failed organically and is lashing out at "the algorithm" with unprovable assertions).
