We really need to stop using the "scam" word as a sort of synonym to "bad service"; because obviously there's a HUGE difference between the two.
PayPal's cryptocurrency-related services are definitely very very limited, but it has been the same with Cash App in the past. The likeliness of what's going to happen is, it's a slow rolling out of features; because I'm pretty sure PayPal is totally aware that bitcoin is really hot right now, and it's smart for them(business wise) to take advantage of this hype and roll out their buy/sell feature asap.
This is what I am looking for.
People tend to use scam so much even if it is just a bad service.
I haven't use or read the TOS of Paypal regarding to crypto or Bitcoin but I know that one thing OP tells is true if we use them as Bitcoin wallet we wouldn't own or hold our own private key.
And I think it is only the beginning they would improve their service in the future (Hoping for those who would use their service as a crypto wallet).
