If it was something that the community agreed on, I'm not fully against putting ads on Steemit.

I'm against targeted advertising, because it involves tracking and thus privacy invasions. Sure it could be done responsibly but the most profit is to be gained by sharing as much information between you and the service as possible, and allowing them to hold on to that information, or even own it for later resale.

As all advertising (really, all of it) is targeted advertising nowadays, I am forced into the position of rejecting it outright.

I do personally hate advertising as it appears to me to be manipulative and soulless. However that's just for me personally and I don't disagree with it in general on any moral grounds. I've bought goods and services on the back of an ad many times.

Would you put ads on your page if you had the option?

I would consider putting an ad on my page if I could be convinced that no tracking whatsoever would be involved, and if I would have the choice of what ad was there.

Oh, and one thing to make clear here too is the difference between the Steem blockchain network and Steemit.com, owned and operated by Steemit Inc. If steemit.com introduced tracking ads on the site, I would stop using it immediately and switch to a competitor. If no such competitor existed I guess we'd be looking at forming a new one!
