The speeds are as fast (or slow) as the slowest member in the chain. If most people who participate have slow connections, then most of the times it’ll be slow. But if the majority uses fast connections, then most chains/tunnels will be fast.
Again, it’s a chicken and egg problem: people who want fast downloads (and thus have fast pipes) won’t participate because it’s slow, but in doing so, they miss a chance to be part of the solution.
After I got a good job, I started donating to FOSS projects. They have already proven to be useful, unlike other crowdfunded projects in the inception stage. My bill for software now exists for opensource software, whereas when Windows was my main OS, it was non-existent. I love the option to give money. That’s freedom.
Sure, but why aren’t those vendors certified? Is it a lack of action on the vendor’s part? Is it a monetary problem where Canonical is demanding too much money and thus gatekeeping smaller vendors with smaller pockets from being certified? what is it?
