Some things are hard cause we end up seeing only our side. For most people this question is a matter of who you are in this interaction

I click the little turquoise "Show me how to disable" button, and then immediately click the "Continue to site" button without disabling any of my ad blockers. I fucking hate being advertised to everywhere I go IRL, and it's become even worse on the internet. Commercials interrupting my music, my videos, my TV shows, my movies, news articles, every fucking thing. I see it like this: If they need to advertise this much to keep the lights on, then they would not be making a profit, and they will have to shut down (because they'd never give up their profits willingly to keep things going), and if enough sites have to shut down due to costs, eventually the costs will threaten the providers having to shut down due to lack of sites, then the costs will come down, and the cycle starts all over again. They agreed to allow advertising to make profit. I did not agree to be advertised to. They gain profit, I get a headache. This is not a fair arrangement for whomever they are forcing their ads upon. Honestly, I feel they should do away with ads entirely. If they can't keep the lights on, they can charge a ten cent fee per article to read it. I'd gladly pay a dime to read a good article, and those dimes would add up. Otherwise, I don't much care about how poorly they are handling their finances without ads.

i use uBlock but some cites can circumvent it. i've never bought anything advertised on-line & i really wonder how many ppl do. FB & google seem to be making big profits so the advertisers must think that their ads work. sometimes i think the whole phony economy & false prosperity are built on the promise of everyone buying everything on-line. and not just what they need but more.
i can't help bu feel that one of these earnings seasons ppl will start to realize that all this supposed wealth is just an illusion.

Not your call...always take what you are given, or block it. And BTW, more memory will stop those "slow-diwns".. I use a samsung (cheap!) 10"tablet, with 32 mbits, and have No slowdowns of any kind, ever.
