My current kindle is my third one, and is the last. I will never ever pay for a kindle to Amazon, due to its user hostility.
Oh, and also you cannot move ebooks between accounts, even not with a lot of friction, eg. support tickets, which would be a fair way to game piracy and unwanted lending, which was some inconvinience for me in a situation. Not a huge monetary loss for me, rather a reminder that when you pay to Amazon (or Valve, or any other contemporary DRM-burdened vendor) you are only leasing...
I keep it offline in airplane mode permanently from 2016 and haven't seen a single ad in a long long time.
I have my 2016 one setup without a password so when I open my cover the device unlocks, so I never really even see the ad unless I try.
The ads are only shown while it's off, they're static black and white images, and 99% of the time they're for books. Totally unobjectionable.
If they were in the actual UI and for stuff like cars and perfume I might mind, but they aren't so I never cared.
Speak for yourself. Aside from the principle, some of us don’t want to be advertised to in the comfort of our own home/bed/while we’re camping or whatever. Ads don’t have to be actively flashing, spaz-inducing insanity to be objectionable.
Not to mention that by definition an ad like this WILL be seen and attended to, even if only momentarily. That in itself is also objectionable.
But then I also understand that'd increase the price by 10% and only help right handed people with weak hands so... c'est la vie.
