YouTube's plan backfires, people are installing better ad blockers

This is a most excellent place for technology news and articles.
Honestly, Google did this to themselves with not properly vetting the advertisers that they sell space to, and with oversaturation of ads.
If they'd have stopped granting ad space to scammers and malware spreaders, and if they'd have stopped adding advertisements at the line most people find tolerable (which seems to be a single ad between videos... not multiple at a time, and certainly no mid-rolls), they wouldn't have triggered quite the level of ad blocking that they did.
I see this "problem" that they have as being entirely of their own making.
