It's not always true that a vendor receiving money will increase prices to pass the PayPal fees to the consumer. You can see that many checkouts offer multiple options (e.g. both PayPal, Stripe, and/or other methods), with the item price usually the same even if each method has a different fee. The idea is that you want to make purchasing as convenient as possible, as it costs more to lose a sale, versus paying an incremental fee difference with PayPal.

If a vendor makes PayPal purchases slightly more expensive, it can cause bad will with the customer (who is less likely to return and make more purchases). Exceptions are sometimes with one-off purchases (e.g. a conference ticket or course fee).

Separately, the original comment asserted that the PayPal account charges you each transaction (which is false). The new argument is different, which asserts that a vendor may charge you more due to PayPal fees.

You misunderstand me. I didn't say you got charged extra for paypal over Stripe, for instance.

Stripe which you mention is also expensive, and also factored in to the price. I don't know of any serious eccomerce company that is not acutely aware of card fees. Every payment gateway charges high fees and it is factored in to the price the consumer pays.
