I'm not aware if you can do it the way you mention, but you can used NextDNS and it pretty much cleans most of the ads (I actually haven't seen an ad in a very long time).
I don't know about any research on the matter, but I can say 2 things that worked very well for me:
1) take an intensive course first
2) then live in a country where the main language was the one I learned
Granted, point 2 isn't easy, but nothing can beat it.
The most important point is to use the language on a regular basis. If you don't, you'll forget it quickly.
I agree, the bootstrapping trust is a hard issue, and I don't think either that a distributed system will magically fix things. What would happen is we'd just change one set of problems for another one, but IMHO it'd be a better system overall. In this case, making things more visible is a better thing. That's an interesting point about the way a distributed model would evolve. My question is: does it matter? If we could more easily spot a bad actor, wouldn't it make everyone behave better?
He was probably talking about the centralised model used with CAs, and trying to start a discussion about an alternative to the CA model, probably some way of decentralised control, hence the bitcoin reference.
Convergence [1] comes to mind.
So this ends up being as "simple" as answering the question: Do you trust Apple? Given they control the operating system and all around it, having the directory server controlled by someone else (or distributed) doesn't solve the problem as they have access to anything they want in your device, meaning they don't need any keys to begin with.
I disagree. If things go south (meaning they do what they claimed they couldn't, and then get caught) people will surely remember it, and in that case it would be negative PR-points, doubled.
That doesn't mean he's not lying, it just makes it less likely.
I agree education is a big problem in Brazil. IMO, the main issue is this culture around not asking questions so it won't look like you don't know something. As a consequence, getting involved and going into depth to really learn something just isn't that much encouraged because it would require, well, asking many many questions!
Exactly. That's more than impolite, it's unfair IMO.
If the only way they can offer a better service is by screwing with the competition, well, they aren't doing a very good job then.
Otherwise they could spend their time looking for ways to improve their services.
