I know exactly what you mean and I've had the same. Some people have encouraged her to do what I've just told them I'm trying to teach her not to.
I feel rude asking them to back off as I know they don't mean any harm but i don't want to teach puppy that she gets rewards in strikes and hugs etc for ignoring my commands.
Once when puppy was about 12 weeks, this man kept trying to stroke puppy but she was terrified of him, I asked him not to try stroke puppy and just let us past him as he was scaring her, he said "nonesense" and kept trying to reach the puppy, asked agin for him to let me past and which point he said "she needs to learn" and tried to pull the leash and dog towards him to pick her up. I picked my puppy up and walked in opposite direction and said he needs to learn that when a woman says no she means no.
I asked dh how he handled this as he's always been the one to do this part of the training and he said it's never happened to him, people don't approach him at all, I think it's something to do with him being a big, rugged angry looking skinhead!
A little puppy jumping up maybe cute and adorable now, but she will get bugger one day and I don't want the type of dog that runs and jumps at strangers. Most people are happy to wait a few seconds, but the odd one will whistle her etc so I started using a bit of an extra firm voice with puppy when I think someone is going to encourage her to ignore me and come stroke, I'll keep repeating sit etc in a firmer voice and she almost always stays sitting, most people hang back a few seconds and then stroke, but if they still keep trying to distract puppy and she goes to jump, I'll firmly tell puppy no and put her back where I had her, and encourage her to do what we were doing before they distracted her, once people realise I'm going to keep insisting puppy listens to me, instead of them they either give up and walk away or wait a few seconds and then stroke and fuss.
I'm no trainer but it's working for me so far, being assertive with the puppy and focussing on her avoided confronting strangers who get arsey at being asked not to distract her and puppy is learning it's me who is in charge, not strangers.
