That's not what flanderisation is. I don't know why you keep repeating this word.
Flanderisation is when a previously varied an complex fictional character gets one or a few of their traits exaggerated more and more over time, until it becomes their entire personality.
E.g. Ned Flanders, who was originally just a foil to Homer Simpson. Friendlier, more devout in belief, less potty-mouthed, physically fitter, nicer (while still attainable) home, untroubled family, etc. He represented what Homer wanted to be and was jealous of.
Over time he was flanderised to just being an uber-religious nut with essentially nothing else to his personality.
Flanderisation is not when people are weary of how technology is being used and will continue to be used by large businesses and governments to track what we do and build extensive profiles on us.
We could also all be living under a social credit score system like in China, but most of us aren't. Just because something could become our reality, doesn't mean we should avoid all progress in that field.
In the end it doesn't matter if it's legal or not. They will do it anyways. Like it was the case with Preditor and the Greek government. Or Pegasus and Mexico. In the case of Pegasus and Mexico, people actually died.
The thing is, vaccines work pretty well, but letting some already corrupt asf corporation (or any entity) implant a microchip in your brain is obviously a bad idea. Please do a favor for yourself and the human race by sitting down for a few minutes and asking yourself: "what could go wrong?".
