Right. Like, my use case for SD cards is for my cameras. I want to take pictures and bring them home across international borders. And a 4TB card would be amazing, though probably not fast enough. I simply don’t put files that I don’t want people to find onto my SD cards in the first place.
If somebody is thanking you, you likely exerted effort on their behalf. So they say “thank you” for exerting effort, and then you respond with exerting effort was “no problem” you don’t need to thank me. You’re welcome would be a response more along the lines of “you are welcome” to make me exert effort.
They’re both fine, and it’s both a generational and locational thing. I personally prefer “no problem” because honestly I don’t mind helping, but I’m also not giving you permission to use my effort at any time. You can have my efforts when it doesn’t cause a problem.
