None of that was an issue prior to 2019 when Sony pulled digital game codes from Amazon, GameStop, Best Buy etc. the PS4 wasn’t converted to subscription only, and games kept getting larger.
And for what it’s worth, this also applies to xbox and Nintendo.
The thread on the PlayStation 4 subreddit when this was announced had
lots of unhappy reactions , so you can’t dismiss this as ‘console warriors’ or whatever.
For many people, alternate stores provide an opportunity for cheaper items, alternate payment methods and easier gifting. I still have fond memories of picking up my FIFA games digital codes from Amazon.
I think far too many here forget they are consumers.
