I've sworn off Sony products - well, as much as one can do so - for the past, what, 20 years? - because of that. It's kind of funny to me because I don't usually have a high opinion of "wallet activism", but one day when I was 20 I found out I had a rootkit installed on my computer by Sony and now they are _dead to me_.
I still hate that they got away with deleting my linux partition on my PS3.
That was a completely useless instance of linux and I think it was only ever done to get around some kind of tax or tarrif on game systems vs generic computers, but those are both beside the point.
When I gave them the money, I no longer controlled the money. It remained and still remains fully functional for them after that and I did not get to reach into their bank accounts and remove part of it or even just control what they can and can't spend it on. They got 100% of everything expected out of an exchange of ownership. And they also got to retain partial control of the PS3! What a great gig!
I don't know how Sony could top this, except possibly by also suing everyone.
