Of course remain campaigned. But that doesn't take away from the fact that leave
1) had help from Russia
2) illigal overspent
3) used military grade propaganda and crusicially propaganda targeting
4) dismissed facts as project fear
5) were deliberately ambiguous about what leave will actually mean.
6) Used Nazi style imagery of 'invading hoards' to play on peoples fears
7) promised unicorn cum style swashbuckling trade deals that would not only take the place of the EU trade but better them.
8) invoked images of the war
I could go on... But I'm bored now, leave campaign was a horrific cluster fudge that conned people in to believing that they were doing the right thing for their country, when in fact they were doing the opposite.
And the remain campaign failed spectacularly. I wont be at all surprised to find sometime down the line they indulged in half what you say above, and other dirty tricks besides.
Remember Corbyn coming out at the 11th hour, with a gun to his head, to say meekly "Err yes, we should remain..." - this was the remain campaign tightening its own noose.
They were complacent, and happy to reduce the argument to the same level as leave, and they lost*.
You frame your argument as if remain barely had a campaign, and the leave used every dirty trick in the book and fooled the poor, unsuspecting populace into voting for them while what campaign remain did have was virtuous and pure.
You also frame it as if targeted advertising made everyone vote leave without them even knowing, as if they were hypnotised, the poor little lambs.
On both counts, I call flimflam.
On both counts, yes, there is truth - but your version is not the whole truth at all. Its warped to suit your ideology and desire to justify a result you did not like (or accept/understand?).
Not just because Russia and Facebook no, I have listed someone them.
As to your second point... Of course it works, I'm not sure if you are being serious not???
I am being serious, just what power do you suppose seeing ads on a news feed really has?
Are you really saying I voted as I did because of them? REALLY?
As I said, I can well see the whole echo chamber/tell people things they already think side of things reinforcing pre existing beliefs, but then the most that campaign can achieve is getting people to vote the way they would have anyway. Which would be a game changer if that part of the electorate was pre disposed to NOT voting. Either way though, its not bloody mind control.
EDIT, forgot to add*
I actually despise the whole campaign, on both sides, and what they reduced it to. It was fundamentally shameful.
