Hillary didn't take any non-screened questions from the press for a period of several months during the heat of the campaign.
HRC campaign was overconfident in swing states and chose not to campaign there.
If advertising can win elections, then Hillary would have won since she far outspent Trump on media. Let's not forget she had a much larger army of astro turfers (Correct The Record) pushing her message on the internet and it was all for moot. It turns out people aren't as easy to sway as advertisers would have you believe.
It is impossible to know the full extent that Russian interference had on the election, but dismissing its impact because there is no proof of its 'effectiveness' is laughable. We know political ads work. It is why every single modern political campaign runs them. A google search gives you a rough idea of the reach this political campaign had. Put those simple principles together and you get why all western intelligence communities are in agreement that russia interfered and affected the US presidential election. Given how susceptible people are to advertising it shouldn't come as a surprise.
When someone posits a statement that is just insanely ignorant (and demonstrably wrong) like "I would even be satisfied with any ad from any country having the ability to significantly sway any election." then the intent to derail the conversation is clear. Any knowledge of political history (and advertising) would tell you that such a statement is clearly ridiculous. Being obstinate and a pedant doesn't make automatically make you a critical thinker. In this case, it blinds you from seeing the obvious.
Some sources for you even though you are probably too busy commenting something contrarian to google this shit yourself.

I would still request evidence about the scope of this, because basic evidence suggests strongly that the influence was minuscule.
So I would heavily question "deeply impacted". Perhaps this whole story was just fake news?
I would even be satisfied with any ad from any country having the ability to significantly sway any election.
There are far more probable explanations for the result of the election.
