There is an old proverb from the late 1990's, if you don't know what product they are pitching;  you are the product.

Historically presidents didn't campaign for votes.  It was considered unseemly.  The first President to campaign for himself was in 1840,  William Henry Harrison.   Vestiges of this remain in American politics where Presidents will sometimes tell their constituents to vote;  even if you vote for my opposition, it's important that you vote.

I would argue there is a more cynical interpretation of getting 21st century, generic non partisan messages to vote.  I would argue that the folks sending you those messages today know exactly how you are going to vote.  Thus a generic get out the vote message is in reality a message to vote for the Donald, or Joe.  Only you and everybody advertising on the internet know's which for sure.

There is no privacy online.  If you use free services such as ( google search, google mail, facebook, stack exchange, twitter, youtube, Weechat )  you are pretty much an open book.   They know everything about you.  They know how you have voted, your income, the charities you support, how you inform yourself, what pitch you would find most persuasive, what conspiracy theories you subscribe too,  and how to poke you to do this or that.   You and your proclivities have been modeled, and sold to Acme Republican or Democratic turn out the vote machine.  In the 21st century when you receive a generic get out the vote message,  it's really like every google search, facebook alert, or unsolicited news story; it's a highly customized way to manipulate you.   That's why the free services companies are worth hundreds of Billions, Trillions of dollars.  Because what they do works.
