I once had a valid office key... But since I reset my computer to often the amount of "free activations" was used up... There where so many hoops to jump through to re-activate it that it was easier to get a cracked key to activate my office version... That's just sick
The problem with ads is not a few ads here and there, it's how it negatively impacts every interaction with those sites:
There was also a report recently that google also screwed their customers (those companies who pay for the ads) where google showed ads as in-stream ads in some auto-running videos in the background.
The whole industey is just broken. Present me with non-intrusive, static ads served from your own site and nobody bats an eye (also ad blockers are a non-issue then)
