No, it’s the same on the Windows side. Personally I like to build a new one in parallel, then migrate. I do plenty of upgrades on desktops, but I don’t think I’ve ever done one on a server (except stuff like CentOS 7 to 8 where it’s not really that significant of a change).
Migration is the safe option, but if it’s a huge pain to migrate, I might do the in-place upgrade with a rollback plan ready if it really goes poorly.
I’m not sure what this guy is smoking, but I don’t want any. He talks about licenses being different from contracts, but there isn’t any significant difference. He talks about developers getting paid instead of releasing their work for free, but there’s nothing stopping anyone from doing this right now. Plenty of products offer business licenses separate from their copyleft licenses. Anyone who releases their software under GPL or whatever chooses to do that, because that’s what they want to do. If they wanted to make it only source-available, or to sell source access, they would have.
Yes, especially in the UK, since they’re a surveillance state.
There are some things that will always get flagged on any platform. This, drugs, and connections to sanctioned countries, for example. I’ve heard of people in the US having their Venmo accounts suspended because they put “Havana” in the transaction description. Havana is a local dance club.
What are you running your containers on? I just put my VPN on the docker host so I could be sure I could use the firewall to block traffic from going out except over the VPN.
