Is it just me, or is Play Store making it harder to scroll when ads are on-screen?
I normally use the Aurora frontend, but I used Google's app to check something. I couldn't help but notice that when I swiped and then let go, the page would barely move past the point I had let go. It had no momentum whatsoever. As soon as I got past the ads, scrolling was back to normal and the exact same flinging motion would send me down by at least a screen's worth.
At this point, the play store has such a monopoly that they can do whatever the fuck they want. That's why there are so many ads.
In my opinion, software that can be considered required for hardware that you've paid for to work (OS/system level apps) should not be allowed to have ads by law. It's also a double infraction when they bait'n'switch you by slowly rolling out more and more ads on a phone you already bought.
There's a FOSS app for just about everything. You can also use Micro G to replace Google Services, so there's almost no reason for using anything Google on an Android phone.
Playing devil's advocate here, the old store system I worked for always inserted cross-sellers at each page-break, too. It was just how the underlying code worked, it first loaded a batch of products, checked whether the user was supposed to see them, then figured out cross-sellers for it.
But by nature of that, if you say load 50 products at a time, you end up with those 50 being in the list of returned objects found, followed by the 5 (in our case) ads. So by nature, once someone scrolls to the ads, a short jitter happens as the system loads the next 50 objects for sale (and the next 5 crosssellers).
It might just be that the ad is bogging down the device, rather than a change to the scrolling behaviour. I've definitely had my phone heat up noticeably when it's trying to load an ad.
