I think the fastest way for Linux to spread is for there to be a cheap gross dirty disgusting commercial version pushed at bestbuy/walmart…etc where people can become familiar enough with it to switch to other distros and out still feel familiar.

I do not believe they limit it themselves, they just follow setting set by others. You can choose to block all traffic from certain counties of you want. Or not.

Doesn’t the lightning network which is millions of times faster than btc alone solve this?
