If you think Paypal has a neg rep in your niches, try the financial advice sector. I had a paypal logo up for the 5% of my clients who wanted to do recurring payments through their paypal account but had to take it down.
The other 95% of the clients would send hate mail (unsolicited) to us about paypal. Our backoffice staff would complain about having to deal with paypal. Honestly, I think one day I was walking on the sidewalk and a dog ran up and pissed on my leg because we took paypal payments.
It was unreal how paypal hate was out there. So I took it down.
