Can you point to some examples? Note that they have to be examples which only apply to one side (I'm going to assume you mean conservatives) and aren't standard violations of ToS.

They suppressed Trump’s account before the election…

> They suppressed Trump’s account before the election…

That fact was public knowledge.

Did the twitter files reveal anything more specific about why they suppressed Trump's account?

It seems to me that merely calling them "Twitter files" is very effective at evoking and implying possibly more than what they actually contain.

This was not public knowledge, it was publicly denied.

Please be specific. They have publicly denied shadowbanning but under a very specific and narrow definition.

> but under a very specific and narrow definition.

Which I think is the standard definition - suggesting Twitter have made up their own is a bit snarky?

> They suppressed Trump’s account before the election…

If by "suppressed" you mean "suspended for repeated violations of ToS even though they'd protected him for months by saying he was POTUS and therefore newsworthy and should be granted much more leeway than other accounts", sure.
