The whole no fruty flavors has always seemed an out of touch rule. Kids using any addictive substances is not good, but a few decades ago it was commonplace for kids to be cought smoking analog cigs. Ecigs are safer and have gotten more people to quit than just about anything, but they are also easier for a non smoker to get into. I think the problem is with how kids are getting access to them (from shady illegal online dealers mostly).

That said before big tobacco got involved the older style nicotine isolate vapes were much better at actually getting people to quit smoking. They don’t give the same level of instant nicotine high you can get from the modern salt nicotine and if you are trying to ween off of nicotine they lessen or remove the cravings. It also helped they weren’t cool, my favorite world I’ve heard people call them was ‘mouth fedora’
