On the one hand. I don’t like this, since I install apps off of Google Play all the time. This is beyond stupid and I hope OEMs doesn’t include it.
On the other hand I just helped a colleague try to get a cheap fitness tracker to work on her phone and the manual took her to a random website for the required app. Thankfully the link was dead but even after I said “I don’t trust this link” she proceeded to try and download it twice.
For her I hope this is enabled by default and scares her from disabling it since I feel she will have her banking details stolen if she is left to her own devices.
