In the past, most business owners would perhaps quietly donate to a party or candidates, but probably wouldn't hang their ideology out in front of people all day, every day. Think about someone like Warren Buffett. He has political views, but they are not something he's out there loudly airing on a huge platform.

And like I pointed out, these are not just any old "political views". It's extremist stuff that in the past would have gotten you ostracized. I'm old enough to remember Trent Lott losing his Senate leadership position, for instance.

Also, because of "network effects", simply providing content to Twitter makes the site more valuable.

This stuff sold well in the 20s and 30s and contributed to the initial wishy washy US response to the start of WW2. Imagine a priest way more influential than Rush Limbaugh rooting for the 3rd reich. Now imagine a rich Afrikaner who doesn't begrudge their precarious social standing.

There have always been business owners who shouted their ideology, and others who were quiet. You might remember some cases more than others, and some have had a louder voice than others, but both go way back.
