I don't feel entitled to use their services.

They put content on a publicly accessible server for anyone to access if they choose to do so. (I sometimes choose to)

They also link ads on the same server for anyone to access if they choose to do so. (I always choose not to)

If they took their content away, I wouldn't give a shit. There are many other things I can, and do, spend my time on.

Since I never paid for their content, and they never asked me to pay for it, I have no expectation of what must happen with the content.

Edit:formatting and spelling.

There's a level of annoyingness I'll tolerate from ads; small text ads or images are fine, autoplaying sound or anything that slows down my computer when I load the page is not.
