Bad metaphor. No one is stealing anything from YouTube. Meanwhile a tantrum is a display of socially unacceptable behavior because you don’t like something.
How is blocking adblockers "socially unacceptable behavior"?
It might frustrate you personally -- the same way it might frustrate you to have to pay money to see a movie at a movie theater -- but I don't see what isn't acceptable about it socially.
bandwidth and hosting have associated costs. unlike piracy, which is just creating copies, this is using Google’s electricity to provide you a service without giving anything in return.
Google is always free to stop serving me anything at all if they choose to.
However, once they serve me something and it’s received by my user agent, I will use that user agent however I see fit to parse and display (or not display) that content.
I’ll rephrase my position: Google is free to ban my IP, require a payment before serving me videos, or whatever else they feel is appropriate to stop me from using their electricity without being compensated appropriately. But if they serve me a page containing a video, I have every right to instruct the software on my device to render that video however I see fit. This in no way is morally or legally comparable to stealing, theft, fraud, or whatever other words people are throwing around.
Very much a tantrum.
