Ah yes, the classic "my business plan is your moral problem; you owe me your eyes on my ads because I'm the idiot giving things away for free."

People don't want ads. You imply that "if you accept ads then things will be free" but they will not. Never accept ads. Not for a free service, certainly not in a paid product. Ads exist to enable leaching in both direction in exchange for what ends up being nearly mind control. But it is two-way leaching - companies benefit without the friction of explicit payment, consumers get a service without explicitly paying via money. The downside is neither can stop the bad-incentives motivating bad actions from the other side.

Ads are a deal with the devil, and rejecting them outright is allowed via that deal, just as companies can withdraw their free service. It cuts both ways.
