I can't see from this article whether "could cost" means there are lawsuits ongoing/pending, or just the author has speculated what the fine could be if there were a lawsuit?
TBH I would not know how to reply. I think your response sounds a bit rude, but not bad - and the other guy ought to take it in his stride and get over it.
The trick - apparently - is to be somehow quick-witted and articulate at the same time as you're feeling anxious and crowded. Something like, "sorry, I'm not in a good space for strangers right now." ...But then, some strangers would take that as a cue of openness and enthusiastically start strangersplaining to you how they're a good'un and it's all alright and anyway you should be more open to people because society's better that way...
So maybe your response isn't all that bad, in the end.
Or, "not at the moment, sorry."
See, eventually I can come up with a good response!
It's still a bit passive aggressive, I would feel.
I think if I were quick of thought (oh, how I wish!) I'd reply something positive like, "sure, what's up?" And then if the request were too onerous I'd say, "sorry, I can't."
I'd like to advocate that - even if it is rude - it shouldn't be a problem. What I mean is, if you ask someone you don't know well for a favour, and you get a rude or borderline aggressive reply, just accept it and walk away. So many of us give weird-sounding answers in the spur of the moment, with no bad intentions. When you hear/receive one of those weird replies, it does no harm to give it the benefit of the doubt.
That misses, if I'm not mistaken, that that wealth is not in available money to use. It's in factories, equipment, structures, land, intellectual property, team cohesion, national reserves, loans to foreign countries.
If wealth were spread around evenly, then the market allowed to operate again, any one person could trade their 'wealth' for spending money and consume food/games/house/etc from it. But if most Americans spent it all as spending money, the country would collapse.
And practical advice: that's (related to) why, if you want to start building wealth for yourself or your children, it's important to put some of your money into 'assets' that are doing something. A new goat for your farm, an improved chainsaw, an educational course, or stocks and shares (which essentially means lending your wealth to someone else to make something with it and they give you back part of the profits). Rather than consuming it all.
Just... Try not to grow it into an empire that exploits the poor and needy for your further benefit.
Does this really need docker, if it's all in-browser? Ultimately, is it just served as files from your self-hosted server and the client browser does the magic?
I use Nebula. It's lightweight, well-engineered and fully under your control. But you do need a computer with a fixed IP and accessible port. (E.g. a cheap VPS)
You can also use "managed nebula" if you want to enjoy the same risk of the control point of your network depending on a new business ;-)
Tailscale is great. The principle concern to me is that your super easy mesh network depends on Tailscale so if they want it they have control, and if they change their pricing or options you depend on them, and though they can't see the data you send they can see the topology of your network and where all your computers/devices are.
I use Nebula, which is more work to set up and doesn't have some of the features, not
But if you slap the 'lighthouse' (administrating node) on a cheap VPS it works great. And it has some advantages. But Nebula also troubles me: though it's fully open source and fully in your control, the documentation isn't great. Instead, you can now get "managed nebula", which puts you in the same problem as Tailscale: the company sees and controls your network topology. I fear the company (Defined Networking) is trying to push things that way. Even their android app you can't fully configure unless you use their 'managed' service.
For now, Nebula is great, and my preferred mesh network (I looked into all the main ones). And for Tailscale you can run the administration server yourself with Headscale and be fully in your control.
Actually I wish Tailscale the best as a profitable business. They've created a fantastic service and system. But for me, I'd rather my network be in my own hands and for my own eyes. And, as is OP's main point, once they have enough dependent users, the service might turn much worse.
Meanwhile women are hand-coding in assembly, like God intended.
