Well-meaning governments or companies might trample on the sometimes “very thin” line between political commentary and an “illegitimate attempt to smear a candidate,”
Such demagoguery as the latter is the rule rather then the exception in many if not most countries in the world, the US included.
With everything to gain and hardly ever anything to lose by doing so, knowingly misrepresenting the truth or outright lying is something that almost all successful politicians do.
Until it’s disincentivized strongly by strengthening rules and actually enforcing existing ones, the trend of disinformation being the norm will only accelerate.
