It's baffling for me living in Russia that modern western societies see everything wrong with dictatorship from a goverment but nothing or almost nothing wrong with dictatorship from big capital. E.g. you can't change your break pads unless you go to authorized repair (literal control over your private property and how you use it) and big platforms banning you from multiple public forums because you said a big no-no word (deplatforming and cross-platform restrictions are a thing)

You don’t have to look very hard to see an enormous number of people expressing discontent at the latter.

To speak to your examples, the right to repair, farmers vs John Deere, the exodus from X to Bluesky, the rise of alternative messaging platforms, the outright murder of CEOs on the street and the beatification of the primary suspect on social media…just to scratch the surface

These are all headlines straight from HN and the fact that you even know about them is the difference.

The fundamental difference is while we both lack any real power to change this, under an actual dictatorship people get jailed or worse for that expression.

Let’s touch base on this again when Dictatorship from big capital means Disney puts me in prison for dissent against the mouse and then offers me clemency if I go to the front lines in their next special military operation.

"big capital" does not have the monopoly on violence (except in a dictatorship, through connections to the "big man").
