Honestly, I’m not against ads, I understand that a site with free articles needs to pay the bills somehow. The reason I use ad block is that online ads have become so intrusive that it makes websites unusable, and the way they track you is way over the line. If ads didn’t completely destroy the experience of reading a website and were reasonable in the data they collected I probably wouldn’t bother with ad block.
Wouldn’t the best term be mercantilism? Power through the accumulation of wealth, but instead of nations it’s now corporations. It’s definitely not capitalist since capitalism is about having competition, and that doesn’t happen without constant government intervention to break up monopolies and trusts.
