Why? It will occur every time you access the APP (like in the browser) from Safe.
To use apps anon you would not store them on your computer would you.
Now I am sure some app will install on your computer if you wish and maybe those will still come with a paid for licence code if you do install on computer. Maybe those apps will consider (if suitable to do so) an online paid for by PtD rewards and a paid for licence to install on computer.
That is one area where an installed app can be rewarded for puts done on the behalf of the user. I can imagine a word processing app could work faster if installed on pc and use safe for work files and users documents. This would allow them to not have paid for licence
It is a feature and why bloat will often not be a successful way to get more “income” as people will move to one that is not bloated and run more efficiently.
My thinking is that for network features they will be a burden, unnecessary and maybe even confusing for the user, app developer and maybe hinder things.
But for other purposes, like in game tokens, gift carding for stores, special projects etc etc they make a lot of sense if used properly.
For network rewards or resource purchasing then its double handling in my view and an unwanted overhead.
