Naughtyware. No, not that sort.
It looks like some app development may be taking a dark turn. Since ebay has released a new version of its app, the old version no longer works on my phone.
I start it, it crashes and then it kindly notifies me that a new version of the app is available.
The new version requires the location privilege, where the old location did not, and now to use ebay on my phone I have little choice but to install it and switch off location services while I use it.
