Or perhaps you believe the mere existence of information is a call for attention.

I think there would be exceptions, like test sites, personal experiments etc. that could make it on to the internet without seeking attention, but any content designed for consumption is attention-seeking.

Maybe. Attention can also be granted without it have been called there. There are also websites not designed for consumption.

If every website is advertising, then surely most of human discourse and activity would also be considered advertising. What's even the purpose of the word?

You're not going to convince me that everything is an ad, and I probably won't convince you either. I'm not interested in playing any further semantic word games. I'll read any replies you make if you choose to, but I have nothing more to offer in this thread.

I do believe all content made for consumption (even purely informational content) is attention-seeking.
