I will use PayPal when making purchases, mostly to keep from giving my payment information directly to yet another company that could handle it improperly.
Not to say that PayPal wouldn't misuse the information too, but it's one company that might misuse my information vs many companies, so I'll go with the one.
In Poland there is a payment system called blik, and it's not a company, but more like a protocol iirc. The blik provider is literally your bank, so no external platform to give your info to.
Although, I'm not sure whether it doesn't share your payment information, since I don't really know how it works internally.
