This title is editorialised. The actual title is "These french villages". Leaving out "these" makes it sound like no french village has drinking water
"French villages" - From two to all, with a bias to "many"
"Some French villages" - From two to less-than-all, with a strong bias toward a relatively small percentage.
Removing the word "some" very much changes how that title will be understood by a native English speaker. Except for me, because I've started to assume that this type of manipulation is the default and so whatever the title claims, the reality will be much less interesting or meaningful or profound.
