"Consent must be freely given, which will not be the case where there is imbalance of power between data controller and subject."
Somebody gets it.
I'm not a lawyer, but my work did involve contracting and formal training in same. The quote above states one of what I was taught were the three fundamental conditions for a valid legal contract.
The other two were a reasonably equitable quid-pro-quo, and a meeting of the minds (that is a common understanding of the terms and conditions.
I have yet to see an IT sales or service agreement that doesn't violate at least two of these. The argument that I don't have to use a given IT product or service is not valid in today's world, where connectivity is a fundamental necessity. (The odds of finding a cell phone in the US if your life depended on it are between slim and none.) As for a meeting of the minds, I can't remember the last time I read an agreement that didn't include a provision allowing the seller to change terms and conditions at will, without notice,
This kind of thing is not unique to the IT sector, as the recent United Air incident demonstrates. The companies have all the power; the customer is forced to accept the conditions or do without what are really basic necessities for a normal quality of life in a developed nation. The average person is powerless, and increasingly resentful. Brexit, the recent election in the US, are key bits of evidence of a deep dissatisfaction that those who govern are oblivious to.
This creates a situation, where the stability of society is dependent on the populace's willingness to leave well-enough alone. History is replete with examples of how precarious that balancing act can be, and how catastrophic the consequences can be when those who govern get it wrong..
