So you think that popups are a good thing? One could argue that the popup killers kill advertising revenue. We have a defender of popups?
Pop-ups are the way through which certain ventures choose to sustain themselves or make profit. How do you define "good"?
If it is profitable to the users of pop-ups, it is a good thing
to them. However, if it keeps away customers, it is a bad thing to the ventures. It is a discomfort to the web surfers, however it is not a bad thing since it rarely intends to "harm" you (I am talking about legal pop ups, not endless loops).
The legality of pop ups remains questioned, but so far the law supports the position of the ventures using them. It is ethical to use them according to the law of the country you live in.
Therefor, increasing your comfort by disabling pop-ups is, universally, the un-ethical thing to do, not vice versa. Therfor, sites who annoy you for disabling their pop-ups are in NO WAY unethical. Actually their claim is perfectly legitimate: One of the conditions to visiting our website is suffering our popups. We are those incharge of the content, therefor it is perfectly legitimate for us to make you see them for using/reading our content. By removing the pop-ups, you change the content and it's advertising appendixes, hurting our chosen financial oppurtunities, therefor making it legitimate for us to display this annoying message.
I'm only ensuring my sanity of surf the internet by not being bombarded with a ton of popups.
(Meant to say 'rights' but I have none in the internet )
If you get an apocalyptic attack due to sudden pop-up advertising, you might have a case. So far the only thing I hear from you is "Discomfort", and considering it is the website and content of the owners of the website, who choose to use pop ups, your case holds no water in the ethical or legal reality.
By the way, I use a pop up killer.
