That's like saying it's your cable box and your TV and you have every right to control what's on the screen, including stripping ads automatically (without changing channels or muting)
I DO have that right and given the technology to do so I'll exercise that right at every opportunity. They are welcome to try to invade my life to sell me stuff but that doesn't mean I have any obligation to let them do that. Their flimsy business model isn't my concern. If I value it then I will pay for it and I sometimes do. Most times I value my privacy and attention more than I value their advertisements and thus I block them. If this results in TV or other services price adjusting to compensate then so be it.
But somehow it's not okay for the vendor providing you web content to charge you money (indirectly through ads)?
It's ok for them to try but they aren't entitled to any expectation that I should have to support their flimsy business model. I can assure you that I am not interested in their advertisements without having seen them. If they want to subsidize their content via ads that probably means their content isn't especially compelling or valuable.
Are website owners creating websites for charity?
I don't care what their motivations are. Not my concern. I value my privacy, bandwidth and attention. I don't give these away for free, directly or indirectly. I'm not about to provide charity to a website operator just because he threw something up and attached some ads to it.
Do you belong to the entitlement generation?
Apparently you think it is ok for content providers to be entitled but not content consumers. Curious double standard you have there.
