It seems like your assumung that pundits and bots already dominate the dialogue to such an extent that normal people can't communicate and voice their political grivances. I don't belive that's the case.
We're learning to deal with new forms of propaganda the same way we dealt with the old ones. I remember when people were talking about the information overload of the early days of the internet as driving people insane. Or people who complained about TV advertising being a form of mind control.
People that can't cope will either succumb to the will of others or retreat but that doesn't mean the rest of us shouldn't keep using these tools to our advantage.
> Yes. Politicians. They also do actual political work.
Isn't it clear that renaming post-offices a few months before they're defunded qualifies as actual political work or filling stadiums of people to give them a rock concert version of the political experience or hosting twitch streams of a co-op video game to an audience of 500k people? You might consider grilling social media companies for not doing enough to promote for their party's interests "political work" but when it's done in a chamber dedicated to governing through legislation and comes of as whining or yet another attempt at pandering it misses any loftier goals you're implying might exist.
