Only trusting western, mainstream sources that are generally friendly to the Capitalist order is pretty low in terms of standards. Purely trusting biased sources isn’t a good thing.
Moreover, the basic facts weren’t wrong, I pointed out how Britannica intentionally leaves out key details, and emotionally charges the facts it does represent. You’re only getting a small portion of the overall history and are deliberately refusing to look into actual sources, just summaries from biased individuals.
Why don’t you want to read October, by China Mieville? As far as I know it’s seen as very in-depth and well-sourced, the worst you would be doing is getting a better understanding of events.
All of that still doesn’t address that Socialism was by far better for Russia than Tsarism or Capitalism, life expectancies doubled, democratic control was dramatically expanded, literacy rates went from low 30s to 99.9%, famine was ended, and disparity was lowered while GDP raised dramatically and consistently. Even if we ignored the events of the Revolution, the working class won out dramatically.
You must disapprove of Capitalism to a greater degree than Socialism, then, because Capitalism oppresses the working class, who far outnumber the Capitalists. All systems oppress political opponents, what matters is which class is uplifted and which is oppressed, until class is eliminated as a concept. Moreover, the USSR wasn’t a dictatorshio, but a democracy, you can read Soviet Democacy for more on how the Soviet model worked. It’s even listed as a source on the Wikipedia article for Soviet Democracy, so that should pass your bias checks.
