It's the same in all walks of life with the mantra "it must be OK everyone does it" & then many of those who genuinely care give up fighting back.
My Dad always said never to buy cheap tools, but always added that cheap is about more than price.
I've just been offered a really useful piece of software to trial in my business, really useful, but...
the contract allows them to harvest all sorts of "usage patterns & subsequent locations".
This means that in exchange for free use of a tool (actually to make it work there's a few quid to spend, so it's a cheap tool) that will be beneficial, I will be providing a front and a back and a side door to everything I and my contacts would do!
My Dad was right.
