You, Opera, obviusly need to earn money, I get it but if earning money is done only by nagging users with ads then it might be a good idea to consider splitting Opera in two different editions, powerful 100% ad-free, nag-free, promotion-free etc browser with maybe some premium features for some monthly subscription fee like 1-2$ and an ad-sponsored edition.
Opera is still the best browser but it takes a dangerous turn into the world of ads testing us how much can we deal with and still keep using it. I'm telling you, you're on thin ice here and pretty close to loosing your most valued users who recommend Opera to others.
