Do Electrum devs have any donation link? I don't think people won't mind if they do that because a lot of people are using their wallet with satisfaction and it's a pretty good wallet too, easy to use and almost idiot proofed. It's pretty good that they care about their servers but the devs need some love too right?
I haven't seen any donation address on the official website. Maybe there was before, I can't remember but this is what I've seen on the same question if there's a way to donate to electrum.
This is the exact thing that came out when I've searched. It asked and answered three years ago on reddit.
Electrum probably doesn't have revenue as part of its operational structure. As for donations, this was once the reply of the developer:
However, you you can donate to the people who run public Electrum servers.
Electrum does relies on servers, and we currently lack an effective way to reward the server operators.
they don't accept donations. instead they suggest donating to the electrum server you are connected to. you can do that via the help menu option.
Prolly, all of the servers and stuff are gonna run based on its community or otherwise if come short, from their own pockets.
