With BGP, you can easily filter which routes you are going to accept
from your customer - even if it's a bit more tedious to set up.

With OSPF, the customer can just inject you funny things like "hey,
give all packets to google's IPv6 address to me"...

Even if you know that your customers do not have any malicious intent,
mistakes and typos happen.
