I'm not sure what this has to do with e-scooters in Paris though.
Disregarding red pedestrian traffic lights is the norm in France, they are seen as indicative: green means you can pass regardless of traffic as you have absolute priority, red means you must pay attention to cars but you are still allowed to cross and the law supports that. "Jaywalking" doesn't exist in France and pedestrians can basically cross wherever and whenever they want (it's a bit more complicated than that, but not by much).
Cars do have priority when traffic lights are red for pedestrians but they would still be held responsible for any accident.
Thus, it seems to me that your impression stems from ignorance of French traffic law and norms, as the parent said. Visiting a foreign country and thinking all rules are the same as they are at home is always a recipe for disappointment.
Like, now that I live in Belgium I know that red for cars means that one or two cars will probably still go through the intersection and I shouldn't cross (as a pedestrian or a driver) without paying attention. That's not the case in France and I could think that Belgians (or at least the Flemish, don't know about the rest) "have a total disregard for traffic rules" but that's not true, it's just one difference that you have to be aware of.
