content: Ah, but there is an arms race going on between companies that pay their engineers to code their website to thwart ad-blockers and the horde of part-time coders trying to thwart the code that stops the ad-blocker from blocking ads. So far, the pro-adblock camp is winning. I imagine this will continue until services start encoding ads directly into their video feeds, but that doesn't seem practical. It would require a lot of server power to encode the target video plus the customized ads and send all of that to the end user rather than cramming the data down the pipes piecemeal.
