It is similar to a door-to-door salesmen knocking on your private property. He will knock and attempt to entice you to buy a magazine subscription, but you have no intention of buying. He however came on your private property (your computer which you own, the IP which you pay monthly for from your internet service provider, and the browser you downloaded) So at that point that the magazine salesman decides to "pop up" at your doorstep and even though you "browse" through a magazine with no intention of buying, he still came to you.
When you go on YouTube or type a search on Google or see a sidebar that bombards you with contextual ads, you have to watch the commercial in order to view the video. You are essentially paying to watch the YouTube video by watching the commercial. If you have an ad-blocker, you aren't essentially preventing the advertisement from running in background. The advertisement is still running, just prevented to be shown on your browser. Just like a door is preventing a salesman from just walking into your home.
1:1. Whenever a person steals property that is worth a p'rutah or
more, he transgresses a negative commandment, as Exodus 20:13 states:
"Do not steal." Lashes are not administered for the violation of this
commandment, for one is obligated to give compensation. The Torah
requires a thief to compensate the party from whom he stole, whether
he be a Jew or a gentile, an adult or a minor. 1:2. The Torah
prohibits stealing even the slightest amount. It is forbidden to steal
as a jest, to steal with the intent to return, or to steal with the
intent to pay. All is forbidden, lest one habituate oneself to such
conduct
- M. Maimonides, MT, The Laws of Thievery, G’neivah 1:1-2
With the question of intellectual property, purloined property must have a physical existense in order to be considered stolen.Parashat Mattot-Mase’i, Numbers 30:2 – 36:13 Digital material doesn't even exist so how can it be considered physical property? That's subjected to be debate though because if I was playing a video game (Grand Theft Auto) and bought digital drugs from a fictitious digital drug dealer, that doesn't make me an addict nor did I do any monetary transaction other than pay or borrow from a friend the video game itself.
You shall not kindle fire in any of your dwellings on the Sabbath
day (Exodus 35:1-3)
--which extended to electronic devices. *Digital transactions are still "fired up" and a mixture of binary 1's and 0's forming a digital product that is transmitted on a digital highway between two points. So purchasing ficticious digital drugs may not be against the law nor cause harm to my physical well being (still frowned upon) but the act of turning on my computer or laptop on Sabbath is forbidden. That must imply that digital devices and it's software has a physical component, making digital products the worth of a p'rutah or more. You're paying for energy distribution in the form of a digital and electric transaction.

laws.][3]]3

Digital music had to come from the intellectual property of the artist's mind. Furthermore, he didn't just create the music by imagining it to an MP3, he had to pay for it's recording, the recording software (also digital property created by someone which manifested into a physical reality, in which you have choice to purchase a digital copy of binary or get a physical disk sent to you.)
You shall not steal; you shall not deal deceitfully or falsely with
one another. You shall not swear falsely by My name, profaning the
name of your God; I am the Lord. You shall not defraud your fellow.
You shall not commit robbery.
But who is stealing from whom?
Is it the responsibility of the buyer to care for the sellers profits? Had the company purchased digital advertising at a flat rate rather than pay-per-click, it would eliminate the possibility of sabotage or uninterested buyers? If a user decides to use a pop-up blocker then it would further remove an unprofitable market, so chances are people who aren't interested in buying in the first place has the advertisements blocked to begin with.
There was a time I went to Target, and I'm pretty sure I only came to buy one item, then ended up buying a bunch of items I didn't really need. You should've seen the look on my face when the display read I had to pay $306.00 when I came to buy a lamp. I can't always determine the variables or the environment that will prevent me; or not, to buy something. It would be like someone renting a booth at a flea market then being mad at the traffic walking by for merely searching for the food court. So they stopped before eating to check out the wares. Is it wrong that they were thinking of eating a funnel cake? They may eat the funnel cake, come back, and actually buy it later. Or they may go home, get it online somewhere else. It's their choice. The booth owner is in sales, that's the way of sales. You compete with other companies.
